Invoice description not reflected on Checks

When processing invoices in Oracle at the Dashboard level, you have the option of putting in a description of the invoice.  The description we enter on the AP Dashboard however, does not transpose to the check.  Instead we get the description of the purchase order that was entered at the requisition process.  We would like that any description that is entered at the AP Dashboard level be transposed to the check.  How to achieve this feature.

Thanks.
