Change default on Activity Feed to be "Select Location" instead of All Posts.

I created a House for AOD Reports and added just those people who need to see that report, but it requires changing the “Post to” in the Activity Feed from All Posts to this AOD Report house so that only those who should get that report do instead of everyone who has access to viewing all posts in the Activity Feed. Make it a mandatory field before posting so the user must select a location.
