Single Document for Payment in F110

When making payment to Vendor (Employee) through F110, system is posting document for each vendor items.

ex: Vendor 1 10dr Bank 10cr document no: 1000001

Vendor 2 20dr bank 20 Cr Document No:1000002.

But i need to post single document for bank account ie

Vendor 1 10dr

vendor 2 20 Dr

Bank a/c 30 cr Document No; 1000001 (is required)

How to do this?? Any favorable answer is expected urgently.
