Complex scenario for paypal

[mzohaibniaz]

I am using paypal adaptive payments with Preapproval request. Buyer "A" buy 2 items from Seller '1' and 3 items from Seller '2'. Obviously, our app take commission from each seller. But this will be the preapproval request, buyer approve payments and after some days i.e. 20 we make an pay call and payments deducts.........

but the problem is, in this request there is two transactions

1. Between app and seller 1
2. between app and seller 2

how to handle this in one transaction?
