Intercompany pricing changes

Can you send suggestions for pricing changes in intercompany process. I am not seeing a spot to suggest pricing change, or change pricing on a PO side.

What we do is we first change the SO price and then send a suggestion to change the PO (SO entry - actions - suggestions to linked PO). When you accept it in the buyer company, you have the option to change the PO line price, qty’s, etc.
