Alias feature containing all villains - looking at vpip?

[WhatAStupidQuestion]

I would really like to find out average VPIP (and other stats) of a pool of players in my database, not including hero stats (who skews the sample).

I was advised by Ubrkey here that notecaddy premium alias feature could help me achieve that.

I understand how I would make an alias with all villains (though I don't know how to do that quickly), BUT when I have this alias, how ould I be able to see the VPIP or other stats of this group?

Thanks in advance for your help.

If you do the positional analysis, don't create the alias.
