Transparency Mask for Widgets

I am trying to do something a little bit weird, but hear me out.

I am currently trying to create a material of sorts that allows there to be transparent holes within a widget that could be moved around, and if there is another one close it can smoothly transition. The thing is, I can’t seem to figure out how to do this. I’m not very experienced with materials, so I kinda suck at stuff like this. If any of you guys have any suggestions that would be greatly appreciated. If you need more detail please let me know and I will try to help. T.I.A you guys.
