Pro site, hardcode pricing table

Hi,
I have a custom pricing table on my site with three plans and only a monthly payment option. I need to integrate this table in the Pro Sites checkout page. But the problem is that Pro Sites generates it's pricing buttons dynamically etc... Is there a way to hard code a button for each plan? I think it can be done with the $level variable somehow.
Any help/suggestion will be very very appreciated

Thanks in advanced.
