It is possible to recreate compatible Helix patches in the Pod Go, but you have to do it manually. I've got a recreation of the Glengarry Lead on the CustomTone page. It took maybe five minutes (very simple Helix patch).
If I remember right from the cheat sheet, to enter snapshot mode, you press the down-bank and up-bank buttons at the same time. I assume you get out of it the same way.
