Serving PAC files via iFile and maintenance of PAC files without full access to tmsh or gui

Ok, quite new here so please be nice :)

So the plan is to to use an iRule to reference an iFile serving out a pac file. There will be a couple of pac files for different groups of users.

This is great and i'm reading up about it. But I as a network designer / TDA don't maintain the content of the pac file. Is there a way (without giving the users full system access) to authenticate other users to update / replace the pac files?
