Clarification needed, are you trying to connect from one Receiver to ten (senders)? RGS has directory mode which allows you to connect to multiple senders from one receiver. When collaborating, it is multiple people (receivers) connecting to a sender and sharing a session. The primary user who starts the session either can accept people to collaborate or there are properties you can use to automatically accept collaborators. If the primary user disconnects or signs out, all other users will be disconnected.
Please review page 59 for directory mode and page 35 for collaboration in the attached user guide.
