When creating a filter in Dynamic Groups based on Static Groups, you currently have to specify the exact value of the group, therefore it's currently not possible to use partial string matching (i.e. starts with, contains, ends with) against static group names.

Where this comes in handy is if you use a consistant naming convention to group devices, for example, we use a consistent format of assets.students.<school>.<department>; so if I need a dynamic group for all student devices I have to ensure I keep that dynamic group filter updated with each new assets.students. device group because the only operators available for Static Groups is either equals or not equal to.

Adding the ability tu use starts with, contains, or ends with operators to Static Groups would mean I could create a single Static Groups filter starts with = assets.student. and not have to remember to update the all.student_devices group; which then means I can rely in any profiles/apps scoped to all.student_devices to be assigned to any new groups that start with the assets.student. string.
