Choose owner in shipment line

Summary:

We would like to repeat the question we asked previously, to which we have not received a response

Hi,

we have on hand quantities of a specific item and lot. This on hand is owned and also consigned, owned by two different suppliers.

When we create a transfer order for this item/lot and try to ship it, we cannot select the owner. So we don't know if we are shipping a owned on hand or, in case we are shipping consigned on hand we don't know which supplier is the owner.
