Downpayment clearing for opentext automatic invoice posting

Hello everyone. My client is using OpenText VIM ( Vendor Invoice Management ) for incoming invoices. VIM automatically triggers FB60 (in case of PO invoice) & MIRO ( In case of PO invoice ). The invoice posting happens automatically in the background which doesn't allow automatic vendor downpayment clearing against these invoices ( done my a 'down payment clearing' push button in normal circumstances in MIRO when posting the invoice manually ). My client doesnt want to use F-54 for downpayment clearing after MIRO.Many of your clients now-a-days would be using automatic invoice posting , how are you guys managing the automatic downpayment process. I would really appreciate any kind of help. Thanks in advance
