Nobody knows anything? :(

I don't think the link is behavior you can create after the dropship has been made.

I think the same thing, but in that case, what would be the correct process to add a new item to the previously created PO dropship? Create a new PO dropship? That only complicates the process 🤔

I am not sure there is a good process for adding items to already made dropship PO's.
