Pop-Up warning when trying to Dispatch a large number of work orders

We have had a few instances where users accidentally select all active work orders and hit Dispatch. This creates a large amount of work to get everything back in teh state if belongs. I would like a warning message when the user has more than 10 WOs selected and hits Dispatch. The warning would say "You are about to schedule a large number of work orders. Are you sure you want to proceed?"
