Atomic - roll your own pnd? No too hard even at commandline until ED or others get their GUI tools out
links to mkisofs and mksquashfs at libpnd hub wiki
it might not open due to being squashfs and not iso? Btw if you hack on the iso you might lose the appended icn and pxml so be sure to reappend the pxml

I wish i had some free time right now, I'd roll a basic pnd-maker ui up hoping someone else can do it
