I agree. For example, most Lionel buildings that have electromechanical activity have 3 wires going in. 2 wires power the lights all the time in the building, and the 3rd wire activates the motion...commonly triggered by an insulated-rail section.
If anyone who has a forklift-equipped building wants to attempt a modification I think it might be fairly simple electrically. OTOH, I understand Menards buildings can be difficult to dis-assemble.
