Saved Work types in Maintenance Event Screen

Hello all-
It would be very advantageous if users could save "Kind of Work" codes or categories similar to how the list of Custom Events is managed.  This would allow the client to build standardized maintenance related events and report accordingly.  Example: Driver Inspection, Lights, Brakes, Flat Tire.  This would expand the functionality of the maintenance tracking to include unscheduled repairs without much effort. Allow the list sort on key entry like other look ups.

We have attached screenshots for clarification. 

Thank you for consideration. - Greg
