Is there way to get multiple files with the GetAttachment function

Hello,

   Is there a way to pull multiple files with the GetAttachment function?  I can successfully get one file, but my requirement is to pull multiple xml invoices from a vendor's sftp site.  I have tried CopyAttachments, but that did not work.  Our current process uses batchruns to download the file and we are trying to get away from doing batchruns. Any suggestions would be helpful. Thank you..
