 * ``bool isPlannableBuilding(df::building_type type, int16_t subtype, int32_t custom)`` returns whether the building type is handled by buildingplan.
 * ``bool isPlanModeEnabled(df::building_type type, int16_t subtype, int32_t custom)`` returns whether the buildingplan UI is enabled for the specified building type.
+* ``bool isPlannedBuilding(df::building *bld)`` returns whether the given building is managed by buildingplan.
 * ``void addPlannedBuilding(df::building *bld)`` suspends the building jobs and adds the building to the monitor list.
 * ``void doCycle()`` runs a check for whether buildlings in the monitor list can be assigned items and unsuspended. This method runs automatically twice a game day, so you only need to call it directly if you want buildingplan to do a check right now.
 * ``void scheduleCycle()`` schedules a cycle to be run during the next non-paused game frame. Can be called multiple times while the game is paused and only one cycle will be scheduled.
