Vendor Partial payments in line with automatic clearing

Dear team,

I require inputs from you regarding clearing the partial payments (Vendor) with automatic clearing. Is this concept possible in SAP??. Currently client is using F-53 t-code for clearing the partial payments manually. But is there any way we automize this functionality. I suggested giving fixed percentage for clearance and this is not possible as per their standards. Payments cannot be in fixed percentage, is their option of developing the same through BDC functionality??. Inputs\suggestions most welcome.

Thanks & regards,

Geo George
