Hi,
my bad, I didn't understand correctly for the first time.
If you are server admin and you cannot Grant this permission then you don't have Grant permission access for this command. You would have to do this via server query then or add yourself to default group (Server Query Admin) which will have this permission granted for sure.
If you decide to use Query box, type this:
Code:
use sid={server id here}
servergroupaddperm sgid={group ID here} permid=4878 permvalue=1 permnegated=0 permskip=0
