Segue to different UITableViewControllers from a single UICollectionViewCell

I have a simple application with a UICollectionViewController that has been designed in Storyboard. There is a single cell (UICollectionViewCell) that I've designed in the UICollectionViewController because it is dynamic.

My UICollectionViewController is called Videos and I have a custom subclass of UICollectionViewCell called VideosCell where I have an IBOutlet from Storyboard to a UILabel. Videos is populated using a NSArray of Languages. Within Storyboard, I also have 2 UITableViewControllers; one called VideosFromVideoTab and another called English Topics. I have set up a segue from the VideosCell in Storyboard to the LanguagesFromVideos and then in prepareForSegue, I have the following:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{

    NSIndexPath *indexPath = [self.videosTabCollectionView indexPathForCell:sender];

    [self.videosTabCollectionView deselectItemAtIndexPath:indexPath animated:YES];

    VideosTabCollectionCell *videosTabCell = (VideosTabCollectionCell *)[self.videosTabCollectionView cellForItemAtIndexPath:indexPath];


    if ([segue.identifier isEqualToString:@"languagesFromVideoSegue"])
    {

        if ([videosTabCell.videosTabCellLabel.text isEqualToString:@"Chinese\n汉语"])
        {
            LanguageFromVideoTabTableViewController *lfvtvc = (LanguageFromVideoTabTableViewController*)segue.destinationViewController;
            NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Chinese Videos" ofType:@"txt"];
            NSString *testString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];
            NSArray *listOfVideos = [testString componentsSeparatedByString:@"\n"];
            NSMutableArray *availableVideosToPass = [listOfVideos mutableCopy];

            NSString *theSelectedLanguage = @"Chinese - 汉语";

            [lfvtvc setAvailableVideos:availableVideosToPass];
            [lfvtvc setSelectedLanguage:theSelectedLanguage];

        }
Etc

So I am checking this segue identifier and then checking the language of the label to see what happens. That works very well.

However, in my head, for the English language, instead of going to VideosFromVideoTab, it's supposed to go to the English Topic UITableViewController, so I thought I could set up another segue with a different identifier and then just check that in the prepareForSegue.

Issue

However, in Storyboard, whenever I set another segue from the VideosCell, it keeps only one. So if I had a segue from the VideosCell to the VideosFromVideosTab UITableViewController, it keeps that, but if I set another segue from the VideosCell to the English Topic UITableViewController, it removes the first segue.

In a separate area of the app, I have a segue from a single UITableViewCell to two different UITableViewControllers. Am I missing something obvious that's stopping me from doing this from the UICollectionViewCell?

Any thoughts would be appreciated!

You do have to use push programmatically.

FirstViewController * controller = (FirstViewController *)[self.storyboard instantiateViewControllerWithIdentifier:@"FirstView"];

[controller setAvailableVideos:availableVideosToPass];
[controller setSelectedLanguage:theSelectedLanguage];

[self.navigationController pushViewController:controller animated:YES];

And for second 

SecondViewController * controller = (SecondViewController *)[self.storyboard instantiateViewControllerWithIdentifier:@"SecondView"];
[self.navigationController pushViewController:controller animated:YES];

In such way you could send to number of ViewControllers depend on selected cell.

If you need more than one segue from the cell, you have to set segues from ViewController to ViewController with different ID.

Then catch Cell select and in use 

[self performSegueWithIdentifier:@"id1" sender:self];

or

[self performSegueWithIdentifier:@"id2" sender:self];
