MIRO Reference to purchase order item

Hi, All.

Scenario: I have a file with more than 300 lines with PO and items to post in MIRO. Currently, this transaction allow to paste 8 lines (PO + item) and then scroll to paste again and again. This means a lot of work for all these items.

SAP Version 605 (SAPKH60521) allow to reference a list of PO without consider PO item (program RM08RL82).

Do you have any idea how to be able to paste (reference) list of PO + item?

Thanks in advance.
