Scaler 2 Custom Guitar tuning (Or even just C)

Specifically, it would be great to have normal C as a tuning (C-F-A#-D#-G-C)

But even cooler would be to have the UI allow for adjusting the root note on the fret board to anything you want.

That should theoretically allow a user to go crazy with any tuning they want. You could still allow for the current list of set tuning items but anything would then be possible.

Are these tuning instances stored in a file somewhere? Could I, for example, edit a file somewhere to allow for this?

Thanks in advance.
