Currently the work log displays all the technicians in the pick list.  For companies like mine who have a large number of technicians, it would be useful to be able to filter by the group.

 

I suggest that you add a pick list for the groups. If a group is selected, the Technicians pick list only shows members of that group. Otherwise it lists all technicians.

 

Techs should be able to select their name without selecting their group if they wish (useful for smaller organisations).

 

You could also provide an option for admins to turn on/off filtering by Workgroup in the work log.
