Paypal Chained Payments MarketPress and ProSites

I have a complicated site (of course everyone thinks that.. lol)

1) I have products that will be sold, and affiliate payments are to be paid to up to 5 levels of people. I've shut off the global products and added the paypal chaining gateway only to be set up.. These products are ordered each time they want them set up as single sales, there may be a future option that we need a recurring type of order, but for now, it's the single order.

2) We are also doing pro sites, and need to be able to do the paypal chaining with that... Since you've done it not he market press side, I'm assuming that it can be done on the pro sites side as well...

So my questions are
1) can we add multiple receivers in market press. If so, how, right now I only see one set...
2) can we add the Paypal chaining gateway to ProSites as well, or how soon...

Thanks
