Match multiple lines to the same purchase order in AP

We have a business case where we need to match multiple lines against a PO to allow coding to multiple subledgers in P0411/P4314 but I don't see a way to do it.

We may have a OP for $100,000.

An invoice will come in for $10,000.    This invoice needs to be applied to two subledgers.  We do and Order to Match, modify the Amount to Voucher to $5000 and populate the subledger type and subledger to S|2115.

I can not find a way to pull the same order again on the same invoice to allow another line to be added to voucher $5000 to a different subledger.
