Eligible students for Private Lessons

I would like to option to make an "eligible students" list for private lessons so that you can select students that can view this option to book online. Currently I use signupgenius to have my students sign up for timeslots during my availability and then transfer over but I would love to combine it all in DSP. I don't want anyone to be able to book certain lesson types (competition team students vs all rec students vs new students, etc.)
