If this function already exist, please advise me, how it works.

Smiliar to the 'channel client rights' it would be nice if we had a tab with 'channel group rights' permission.

Now i have to add every client to the 'channel client' list and edit every permisson manual.
Even easyer if i can add a client to a group which had permission to a specific channel.

exampel: a CA can edit, modify, ect. channel x but dont so at channel y
if i add a second CA to this channel, i must do it manual (and he can do this serverwide, if i add him to the CA group)

Hopefully clear enough, if not, i can explain it on german
