The "Assign to Parent Account" is showing up on a Members Profile in the backend. Can it be made "Admin Only"?

I just made this update. I also updated to hide the form if the user already has a parent. In testing again there is going to be orphaned relationships from the old parent to the new parent if using this function to swap parent accounts or "remove" them.

A more robust process for managing this should be built into the Add On at some point.
