How to change Customer name in a Shipment originated from Transfer Order - Oracle Fusion Cloud SCM

Hello,

i have a general question on the Customer field in the shipment line that was originated from a Transfer Order.

-When i create a TO, the Requester field is automatically populated witht my user name, no possiblity to change this. Here is an example screenshot:

-After this TO is interfaced with inventory side, the Customer field is automatically populated with the same value found in the Requester field of the TO. I can't change this field since it is read only:

i would like instead to specify a different person on the Customer field in the Shipment, we have some cases in which the TO is made for a specific Customer/User and we want to trace this in the system (and on the printed note).
