Using taRMApply eConnect node to apply Cash Receipts to multiple documents

I am trying use eConnect's taRMApply node to apply a single Cash Receipt to Multiple documents(invoices). The MSDN documentation just provides a single field "APTODCNM" . Is there any way I can use taRMApply to apply a single cash receipt to Multiple documents ?
