Script to check for multiple print queues

Experts!  I have a login script that kicks off another script called Printer.bat.  This second script maps print queues based on the group membership of the user account.  Each printer has two Windows groups named after them (PTR-xxx and PTR-xxx-D.  If the user is apart of the first group, the script adds the printer and continues running until it finds a group that ends with -D.  The -D makes the printer the default printer.

The problem I am running into is that the printer.bat script finds the -D group first and doesn't add any more printers.  Is there a way to modify the script to make sure there is at least two print queues before finishing?  That way, if the -D group is found first, it will search for one more group and then quit.  I am including the script I am using (which is compliments of another expert).

@echo off
setlocal enabledelayedexpansion
echo Connecting Printers...
set PriorityDefaultPrinterSet=0
for /f "tokens=1-3 delims=-." %%a in ('M:\ifmember.exe /list ^| find /i "group %UserDomain%\Prt-" ^| sort') do (
  rundll32 printui.dll,PrintUIEntry /in /q /n\\w2k3ps01\%%b
  if "!PriorityDefaultPrinterSet!"=="0" rundll32 printui.dll,PrintUIEntry /y /n\\w2k3ps01\%%b
  if /i "%%c"=="D" set PriorityDefaultPrinterSet=1
)
 
exit
