Give appointment duration range within one service and allow student to choose within range

What specific challenge or problem does this idea solve?

Having to create a different appointment service for each length of appointment (ie 30-Min Lesson w/ Teacher A, 45-Min Lesson w/ Teacher A, 60-Min Lesson w/ Teacher A)

How should this work?

Give a minimum and maximum duration in the appointment/service, plus time increments (ie 15min lengths) then the student can choose the length from a drop down (ie 30min, 45min, 60min)

Who will benefit (Admins, Staff, Students)?

Admin, Staff, and Parents/Students

How will this change impact your daily tasks or overall experience?

This will clean up the appointments services so we can create one service per instructor for each type, instead of having to create a different service for each length of appointment offered for each teacher.
