Love chess, Paid my subscription, Just sitting her

Can RHP add a drop down list that would enable players to specify how frequently they'll make a move when inviting and when accepting a game. Sometimes I want to have a game in an hour or two and move at least once every 2 minutes. If it comes down to the site being able to handle the workload, what sort of subscriptions would you need to charge to have a business case to up the power. Maybe you could have a fast movers subscription rate (and pay me a commission for the idea).
