Switching from a non-admin user to an admin user to run an app
About the only thing you can do in 15 minutes is let the admin account be open to all the non-admin users and have unlocked your library macs to more admins.

Have a look at BootRunner which solves this problem for the entire lab. There is discount pricing and a free trial. Based on what you’re using to manage the lab - your MDM choice may dictate or handle this for you as well.
