Is there a configuration that allows for a single app only to run without going through the lockdown launcher?

I want a selected to application to run all the time like in a kiosk mode, but without having the user be able to go to a launcher type screen and select an app.  SO far I have been able to make a single app be the only choice to launch from the lockdown screen, but I want to just skip that all together and go straight to the app.  

This is for a room scheduler deployment where all we want is for the device to always run the room scheduler app.
