Payment Run - Clearing between Customer and Vendor and Partner Bank Account

Question

Is there a way to have the bank details for the payment to be pulled from the vendor master if an outgoing payment is created or from the customer master if an incoming payment is created? Our requirement is to consider both vendor and customer items during payment processing.  In doing so, if the net of the clearing between the customer and vendor account results in an incoming payment, we want to use the bank details specified from the customer and if the net results in an outgoing payment, we want the bank details on the vendor master to be used.
As such we tick the box on Vendor master to clear with customer and tick the box on Customer master to clear with Vendor.  We have defined 2 payment methods and entered both payment methods on both the customer and Vendor.  We have also entered the different bank accounts on the payment transactions tab of the vendor and customer masters. 
It seems regardless of resulting payment method chosen, the bank details are getting pulled from the vendor master.

Hi,
It is possible without any doing any kind of config or master data changes
While doing F-53, after entering all the required data in open item selection screen, after getting vendor open line items, go to menu item edit->select more.
There enter account type as D and company code (customer account no's comp code) and click on process open items
So you can choose the line items from the other company code's customer also.
Thanks,
