How to add to the Undo Stack in PowerPoint programmatically?

I am programmatically changing the fill color of the selected shapes in a powerpoint slide. I also allow the user to keep "live previewing" changes in a custom task pane. For example,

  1. User selects a shape.
  2. Changes the color of the selected shape by clicking on a color in a custom pane.
  3. Repeats step 2 till satisfied.
  4. Presses Undo.

The problem is, when undo is clicked, it goes back the original color, ignoring all the colors the user cycled through. Is there a way to manipulate the undo stack to allow for going back through the colors one-by-one instead?

You can use the Application.StartNewUndoEntry() API available starting with PowerPoint 2010.

I've never seen any hint that PPT gives access to the undo stack. You might instead want to implement your own stack and give the user a Previous button in the custom pane.
