Update ARR so it skips over units without staffing

Hi there, is there a way so the ARR will skip over units that don't have staffing? For example, I'm training a bunch of personnel from a city PD in SWAT and a lot of PD cars don't have staffing until the training is over. However, choosing an ARR for a police car will attempt to send one of those units and it fails, so I still have to manually assign other units to the call. It would be great if it would skip over unstaffed units and moved to the next staffed one. If this is already possible, can someone tell me how to change the setting?

Good to know! Is there a way to get the logic so it will skip over units that are cross-staffed? The stations where I live have a single crew that takes the engine, ambulance, or ladder depending on the type of call.

Thank you for the response! I'll wait and see if it gets updated in the future.
