On desktop, we have two CylindersModel concurrently: One in the planner and one on the equipment-tab. They act differently, because the former modifies displayed_dive directly, the latter issues undo commands. To differentiate, we used the in_planner() function. However, that appears extremely brittle, especially when combined with undo-commands. Therefore when generating the model, pass in a parameter that says whether this is for the planner or the equipment tab and use that flag to decide how to act.
