In GitKraken, when comparing against working directory, is there any way to get a writeable editor?

Question

I have a stack of commits that I think I am ready to merge to main. I can easily right click on "origin/main" and select "Compare commit against working directory". This gives me a view as if all of my commits were squashed of what changed. Now, as I'm going through this review, I see something in the diff that should be reverted. I'm using side-by-side diff. I try to type into the workspace file, but I get the message "Cannot edit in read-only editor". I could flip to the File View instead of Diff View, but then I can't see the original file to copy from for the revert.

Is there any way to get an writeable editor for the diff view? I've used other compare tools in the past that allow editing, so I know it is technically possible. I'm hoping there's some setting in GitKraken that I'm missing.
