Cloud Hosted Control - ability to set Support Session Default connection on client would be helpful. If end user does not have admin rights ClickRunOnce launch option allows Service Mode to be possible to gain local admin access.
I have found a work around but it involves the interaction from the end user to navigate some options when connecting to a Support Session. Although the end result is possible it is not going to be easy to walk some end users through getting a technician connected since the current Default is it downloads a .EXE client install file.
