Me and a friend were interested in making a board mod with a mechanic similar to a board in Mario Party 8 called "Koopa's Tycoon Town", In this board there are specific spaces which bring up a menu. This menu allows the player to define how many coins (keys) they would like to spend on a hotel in order to upgrade the hotel accordingly. I was considering implementing this but there seems to be no method of grabbing player input in a Board type mod.
