Give SMods more power

[Virtuosofriend]

Okay here is the deal.I just installed a modification for the vb3arcade hack which allows the admins to mass delete a user's scores from the arcade.I thought that i should share it with the super moderators of my forum.However i dont think i can manage php very well yet.So i thought to ask the pros around here for some help.
What i thought was to make a new column inside modcp,which will be viewable only to the supermoderators usergroup.I thought using sth like

if $usergroupid=5;

before the construct command in the index.php but it didnt seem to work because i logged in with a mod account and i could see the option.So basically my question is if it is possible to hide a column inside modcp from all other usergroups except admins and supermoderatos.
Thx in advance.
