Does not stack toggle hot-key?

Has there been any thought about making the Does Not Stack trait toggle on/off?

I’m working on a module that has bridges… These bridges are “towed” to the canal and then set. When being towed, I want them to stack with the towing unit. When they are set, I want them to have the Does Not Stack trait so other units can move over them without worrying about accidentally picking up the bridge during movement. I think I’m going to build two pieces for the bridge - one with and one without this trait - to solve the problem, but the game has 12 different types of bridges which, according to my math, equals a pain in the ass. I’d much prefer a hot-key toggle.
