Alternate sticking notation

I would like to use a French drumming convention, but it isn't available as an option. I'd like to see a sticking palette added that includes upper and lower case letters for right and left hand AND open and closed circles (the aforementioned French notation). For my non-marching band use, this would be helpful. When I make handouts for students, I prefer to use the French notation because it is less confusing for left-handed percussionists (once they get used the notation).

I couldn't upload my pdf to show you the notation I mean, so I've included a google drive URL to the pdf below:

Could this be added as a sticking option?
