Datawedge and RFID tags

I have Datawedge 3.4.2 with the RFID plug.  I need to configure Datawedge that when the trigger is pressed all the tags within reach of the scanner are scanned in one right after the other and when the triggered is released an ENTER key is sent.  Right now, all I can get is each RFID tag is sent with an ENTER key (I'm testing with Word Mobile).  Any ideas on how I can get Datawedge to gather all my RFID tags back to back and send and ENTER key as the last key?
