Allow a bot to modify the roster sent to other Teams users

I'd like the ability to control the roster visibility of participants in a meeting per-participant for a contact center application (although there are certainly other applications).  In this scenario, assume you have Alice (caller), Bob (agent), and Carol (supervisor) in a meeting, along with the bot.  I'd like to bot to be able to show:

• Alice sees the conference roster as "Alice, Helpdesk".  Alice does not need to see the display name of the agent she's speaking with (or it may show an alias)
• Bob sees the roster as "Alice, Bob".  Bob the agent sees Alice's contact information, but not the supervisor (Carol) that's monitoring the call.
• Carol sees the roster as "Alice, Bob, Carol".  Carol (the supervisor) sees the caller and agent information. 

Note that in this case, the bot participant is invisible from all parties.
