Disable "last editd by" for specific usergroups

[K!nG]

Hello all,

I tried to look for this help, but found a lot of old posts with no answer, so creating own thread.

I would like to disable "last edited bye **username** today at **time** for specific usergroup.

I have Show edited by note on edited messages? set to NO in admincp. However still all usergroups including the ones i have it disable for can see it even if i edit my own post or some users posts. I understand i can increase the time limit, but that would be a temporary fix.

I wouldn't want this to be disabled for admins, but just specific usergroups only.

Help will be appreciated.

Thanks
