Is there a way to add a new line in already created PO match voucher?

Hello Gurus,

I have created a 3-way PO matched voucher and now I want to add a new non PO expense amount line to it. While doing so from Supplier ledger inquiry(P0411) it redirects me to 'Voucher Match Reversals' screen. There is no open field to add a line.

I believe we can add a new line to vouchers which are not PO match based and whenever I select them it directs me to 'Enter Voucher - Payment Information' screen.

Is there any processing option I am missing here? Your guidance is highly appreciated. If there is any document related to vouchers kindly provide me a link.
