Add users to multiple call queues at a time

We have almost 30 providers at our healthcare center and each one is a call queue so medical staff can login and answer calls. When we bring a new medical assistant on board, I have to go to each of the 30 call queues one at a time and add the new staff. It would be so convenient if I could go to the user record and have a list of call queues available with checkboxes on which ones to assign them to. In both the members section and as a Manager (since the manager section is the only way that members can log into the group mailbox to check messages)
