Finger numbers in fretboard diagrams

Hello,

I do not believe there is currently a way to have finger numbers in a fretboard diagram. They can only show dots in the position your left hand fingers go. I think it would be a good idea to offer fingers 0,1,2,3,4 for marker types(thumb being 0 since it is rarely used and 1-4(index, middle, ring, pinky) are the standard LH numbering scheme).

Thanks
