Allow Group Admins to send reports with rights of a different user under their management

[#1]

Currently an error is received if a Group Admin attempts to send a report with the rights of another user, which is the expected behavior. We have a use case where it would be helpful for Group Admins to send reports to a user under their management with the rights of the receiving user.

Interesting that I never knew this was a thing since I've always been a system admin. This would be useful especially for group admins when setting up their report delivery for leadership teams.
