F110 issue: concerning house bank change in automatic payment run.

I have a question concerning house bank change in automatic payment run.
Client requirement is to change the House bank between the proposal and the payment.

Step 1 ) Create the proposal run - Bank A is picked

Step 2 ) Change the house bank for the entire run - Use Bank B

I know we have the option to use change it on the vendor level  ( line by line ) or at the item level ( via the "reallocation" button ) but those 2 options are not acceptable since they require manual intervention on each vendor line.

Step 3 ) Run the payment with bank B
 

Is there any way to achieve this in standard ?

I already tried House bank ranking change or available amounts for house banks change between proposal and run.

This does not change the result ( house bank A is picked for the proposal and he payment run )

 

Waiting for quick response on this.
