Give Group Managers the same Sharing Workflow as Member and Owner users

[KatieSteele]

Currently you have to go to the group page itself and click add items to group. Is that difficult? No. BUT, it doesn't match the sharing workflow for the Member and Owner users' sharing workflow. So our team spent significant time trying to figure this out. When we called Tech Support, they didn't know there was a difference in the workflow either, so it just seemed like a bug that we couldn't figure out until I randomly decided to try going to the group page itself and testing to see if group managers could add items that way. They could, but it just doesn't make sense to have them add content differently. That was a waste of time to try to figure that out.  I wasn't able to find anything about it thru google searches either. 

My idea is to make the sharing workflow the same for all users. You should be able to share to a group from the web map/app/etc. itself, and not have to magically know that's how a group manager shares content. 

Just trying to save time and stress for my fellow nerds!

thank you!
