Allow editing of instructors within ILT session

I would like to have the chance to edit instructors within an ILT session- even though we already have registrations for the specific session.

In the current situation we are not able to replace an instructor and / or delete an instructor in case learners are already registered to a session. In daily business, it is absolutly normal that instructors can change. Litmos sessions are not designed for this. So it is not possible to delete an instructor in case he / she is not able to take over the session anymore.
