We are mainly a "Done For You" Agency. Currently if I have a member of my team create social posts in one of the client subaccounts, they can not select my main agency log in as an "approver" to that post. I'm forced to create a "account admin" and then log in as my own "account admin" to approve the post. This is not a feasible solution when an agency is managing many subaccounts in this manner. It is solved by simply giving the Agency Admin and the Agency Users to be in the list of available "approvers". And to further enhance it, add to the granular permissions the ability to be an "approver" on social post so we can further limit who can and can't do the approving!
