CTU Licenses when employee is terminated via "terminate employment"

Hello 

We using a CTU Licenses and every time we terminate employee using “terminate employment” function we have to manually find employee in “shop floor employees” and un-tick “workbench user” box to de-activate/remove the CTU Workbench license from use. Is there another way of doing it so that when employees are terminated using “terminate employment” CTU license also could be removed from user shop floor employee account? 

This is fairly time consuming manual process at the time.
