Automated Addition, removal, and Call group changes.

We are constantly Hiring or offboarding of employees and would like to be able to automatically add their accounts with set parameters, or remove them. Then on top of that. We frequently change the call groups within our 200+ dialing employees, and because of group size limitations, often have to completely remove or re-add everyone to groups when employees work saturdays. so a feature to automatically do the same, add and remove, Users from specific call groups would be even more helpful. It could be integrated Via an API access and code personally on our end if possible. It could save hours of labor every week for Just our company alone.
