Mirror builds

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.
Would it be possible to add a mirror function to the copy/paste button ?

You get a build from the community that you love and want to include in your game but it dont fit into your current map but would if it was mirrored. Same for builders, you built a fab dungeon room and just want it the other way round.

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