If you want just the contents of the PQ moved onto your GPS via GSAK then the easiest way I have found to do it is:
When you import the PQ GPX file into GSAK, in the dialog box, check the box that says "Set user flag" and also check the box that says "Clear all user flags first"
(You can import the GPX file again to get it to set the flags if you have already imported it)
Then use the GSAK saved built in filter for "User Flag (GSAK default)"
Now you should have just the contents of your PQ showing in GSAK.
Now export to your GPS and it will send over just the filtered, flagged caches, which will be the contents of your original PQ.
Hope that helps and that I have understood what you are trying to do.
Thanks a lot for your help with this other option, with GSAK. Have a good time, hohell
