Toggle Base Collision

What Feature would you like to see included within TaleSpire?
What does it look like, how does it work, how is it used. Paint us a figurative picture.
In Campaign Settings, place a toggle that sets the model bases' collision detection to a boolean value. Flipping the toggle turns collision off and on for just the bases of models, allowing them to use collision just for the model itself, which may permit models to more naturally fit into slightly narrower areas on the board.

What situations would this Feature be useful?
Descriptions, examples, interactions with existing features - whatever you can think of to get your idea across!

 This would be useful for situations where characters need to move through small structures with dense prop placement (such as small homes) or through narrow gaps which are occasionally used in dungeons and caves to slow movement progression.
