2011 Brownlow Medal - info/help with betting

Does anyone know any betting agencies that allow you to multi up Brownlow Medal Vote winners per team. I already have Centrebet and Sportsbet accounts and cant seem to do it on them. Thought some of you pros would know??
Would also like to multi up Brownlow, Coleman, NAB Rising Star and Premiership winners but cant do this either.
Any info would be appreciated.
