Sound banks & patches that can be stored separately without replacement

I'm a part time guitarist that enjoys playing and improving and was using Boss pedals that I sold, got a cheap Mooer for $45 that is great for the money and on the go. Just got the GT1 which is fantastic and love the dynamic sound that does a great job of emulating the pedals.

I'm just starting to learn how it operates after enjoying the presets. There is a real learning curve as to how much this little box can do and it is amazing. What is frustrating to me is that downloading patches from BossCentral seems to require installing Boss software on my PC to use and then replace the sounds in my GT1. This is not ideal for me, especially after tinkering around for a while and wanting to make sure I don't erase anything, etc. and prefer a non-invasive method. I have done this all the time with keyboard banks of patches. Is there any place or ability to just download the banks that appear and load them as you will instead of having to have the GT1 connected to the PC and then connecting to Boss Central? Any other go to places that you'd suggest? Thank you for your patience with this GT1 newbie.
