I'm using ASM as the user truth.
Interestingly, as we switch to the new year I see a range of student user records that flip to manual. (It's most likely because those who leave the school are still assigned a device at this point, so if they disappear from ASM they can't yet be removed from Jamf School).
However, there isn't a Filter option to be able to see just those records that are manual (or ASM).
Sure, I can sort the list by Source but it would be more efficient to have a filter.
It is currently cumbersome to clean up student records in the following year. I've run into the issue where I do have two user records for the same person - one from ASM and one manually.
