Post and Update Permissions Settings

I was looking for a way to set the permissions for using the Post rich text editor (as opposed to the Update method via the timeline Post to Feed and the Update on the home page). I was considering if needed, to limit the use of the rich text editor to those with a paid for membership status if needed. I mean; if needed to prevent low quality content from being post to the Post feed. So far, I have not found anything in the Studio that will allow me to do this.
