Flagging schedule conflicts when registering

It would be helpful at studios with multiple rooms and/or class options for similar levels for the system to block out any classes that conflict with ones a student is already registered for. For example, class A for ages 4-6 runs from 3:00-4:00 on Mondays in Studio A so the system won't let the same child register for class B for ages 4-6 which also runs on Monday starting at 3:30 because they overlap.
