Allow Instructor to enter themselves on standby even if currently reserved
As an instructor, I want to have a standby reservation entered and ready to activate when a currently reserved student cancels on me. That way, I can keep myself busy and accommodate other students. Currently, the system does not allow me (the instructor) to enter a standby reservation at a time that I am already reserved. I can't modify these reservations that were made with the previous version of Flight Schedule Pro.
