PO Confirmation tab for SRM POs

Hi Experts

We have an urgent requirement to update confirmation tab in ECC for SRM POs based on information coming from vendor.
Hope you can help me provide possible approach on this.

Also we're checking possibility to use SRM PO response, but this also won't update ECC PO confirmation tab.we

If there's any way we can update this tab directly, that would be a better solution.
Hope you can share your though.

Thank you,
Dex
