How to add new PO line in Inbound delivery

Hello Experts

requirement is to add new PO lines to Inbounde delivery, i mean, not just adding the lines, PO number should also be added & shown in preceding data tab, like, how the data looks when inbound delivery is created wrt PO in VL31N.

is there way to do this?

bottom line is, need to add or combine additonal PO in Inbound delivery which is already created with one different PO.

between i looked at forum, didnt find specific threads, though some related threads are there.

please let me know your thoughts.

Thanks
