Prevent an app from updating after manual installation?

First, thank you very much for the script! I'm now able to use an app again that received an unwanted update on the store that rendered it unusable for me.

One issue however is that the Windows Store tries to update it to the latest version each time I check for updates. I'd assumed that like the Google Play store an app wouldn't update if its signature didn't match, but it looks like the Windows Store will still update a side-loaded app with a different key. Is there any way to prevent this, short of stopping all automatic Windows Store updates for all other apps as well?

Maybe change the repackaged app name? I'm not sure how to do this, but that's an idea.
