On-call access for group member, not just group manager

[shill]

From my limited understanding of the On-Call module, the user listed as a manager has the access rights to create and edit their groups On-call rotations. Unfortunately, not all of our groups managers want to manage this and we are looking for a way to delegate this to a member of the group so that they could manage this for only their group and no other group. I originally thought I could create a new group with the rota_manager role, but that does not limit access to their group membership. In essence, we are trying to designate someone other than the group manager to have the same abilities as that manager for rota creation and editing. It appears that the security for On-Call is controlled by the script include OnCallSecurityNG which I get lost when trying to understand it. Has anyone done something similar or could point me in the right direction?

I wish I could help more, but that was at a previous employer and my current employer does not currently use On-Call. It appears that On-Call has changed quite a bit since my last interaction with it.

Sorry I can't be any more help.
