Do you have access to the SQL via management studio?
I haven't used this for a long time, but i still think it's valid, though i haven't double checked, it ran okay:
Will give you the latest modification date, which is for us normally when they get uploaded.
from sims.stud_student stud join sims.dm_document_710 dm on dm.entity_id = stud.person_id
join sims.sims_person per on dm.entity_id = per.person_id
where stud.latest_adno = '001234' AND dm.attachment_name IS NOT NULL
All you have to do is fill in the admission number for the student. Or remove that clause and you'll get all students.
The name might not be too usable as it includes what look like random characters at the start.
