By unchecking this option, what it really takes away is the ability for a technician to assign a ticket to both "a group" and "another technician within that group".

By the title of that option I would have thought this would still allow the tech to assign a ticket to a group but just not a technician within that group.

So you have an update coming or request yet on being able to offer either or of these options as an ability for a tech assigned to a Role?

in my case, I want the tech to be able to assign tickets to another group, say from their own to another, but also to leave the ticket in the queue unassigned, not allowed to assign a particular technician.
