WNR3500Lv2 - How to create traffic percentage use rules

Hidy ho everone,

I have a WNR3500Lv2 router, thats been pretty good to us so far.  What I wanted to do was to try and create a blanket rule, for every device that connects to my router.  Restricting traffic use, and up/down speeds unless otherwise stated.  That way, I can use mac addresses to give devices more priority as needed.  I know its possible to do that, with specific sevices.  But I don't want to specify a service, I want to use a blanket rule.

Can this be done?
