In my model, workers are performing standard project activities. However, from time to time, I need a worker to perform activities with a higher priority. When all workers are already occupied and no workers are left in the StaffPool, I want the broker to recall a worker from its current workplace immediately to first perform the activity with the high priority. Afterwards, I want the broker to send the worker back to the workplace he was working initially.
Can this be done with the importer/exporter controls of the broker?
