Anyone know if it's possible to include 7 strings into RS? I've noticed a lot of songs that are just 6 string tuned super low didn't know if it was possible to add a string on the fretboard on screen or if you would just have to know how to tune a 6 string properly or understand notes well enough to correctly fret a 7 string while seeing the notes on a 6.

Hey, so I just got a my first seven string guitar and I'm loving it so far. There's one thing though...I want to understand a bit more if there is any that I can do with a seven string. I know everything on a normal guitar but is there some things I can practice or techniques unique to a seven string? I'm looking into incorporating the 7 string into the songs I write now.
