Violin finger pattern diagram

Hello,

I've been messing with editing the existing Fretboard Diagram but am unable to get it to do what I want, so I thought i would suggest a feature if it would be possible. I'm wanting a diagram similar to it that allows for no frets and more than one dot per string to show patterns for different scales on violin. I've included a picture i created in paint to show an idea of what i mean. My example is just showing two octaves, but the string length would need to be adjustable to accommodate 3 octaves as well as the 2nd octaves that require shifting.

If not, is it possible to upload my own custom pictures into a palette and make my own templates that way?

Thank you.
