Hello :)
I tested that method but it seems to be a bug where the code ends up both in bank1 and bank2. In bank1 I can still see the comment -- <CODE1> etc. when I save it in the external editor.
So, it ends up both in bank 1 and 2
Edit:
Saw a potential fix for it on github but I guess I'll have to compile it myself to get it working or?
