consolidated check across operating units for a single supplier

While waiting for the ER for Consolidated/Single Check Across Operating Unit For A Single Supplier has anybody found a workaround to consolidated invoices from a single supplier across OU's onto a single check. 

In the AP documentation (page: 4-42) it states "An example of a payment instruction creation rule is combining payments from different operating units into the same instruction to defray bank fees"

but this functionality does not work.

Thanks!
