Remove Cancellation Permissions?

Hello!

I have a Team Event with 3 Sales Representatives, plus a Sales Manager (which has the Admin role but is not in the event) supervising them.

Is it possible to change the Team Event settings so my Sale Representatives cannot cancel their own calls? Only Reschedule them or set them as No Show.

The Sales Representatives are measured by their close rate, so sometimes they cancel “hard” leads arguing that they don’t qualify, and I would like to stop that. I want that only the Sales Manager can cancel a scheduled call.

How can I do that?

Thanks,
Ángel.-
