Suggestion for Temple, a medalion to blow up a room and turn it into a 4-road room

It's all there in the title of the thread.

i like temple, and i like the direction to turn it back into something with less planning and more activity happening, but i also miss the explosion room from POE1 and how useful that was.

Bring back the explosion room!

I want a medallion that i can use on any room connected to the road (or however it needs to be coded) to blow up that room and turn it into a 4-road room.

thank you for your time.

I'd also like to just be able to place roads where rooms are.

that might be the simpler solution.
