Please make copy/monitor track shape editing of floors.
When I accept a change from a monitored floor the shape is reset if there was previously shape editing applied.
When I encounter such an instance my current workflow is to stop monitoring the floor, copy the floor in again from the linked model (tab, copy, paste aligned to the same place) and then monitor my floor versus linked floor.
Perhaps there is a better solution I am unaware of but copy/monitor recognizing the shape editing would be the best solution.
