Does anyone know how to make the pre-set screen on the MMI remain on the screen when I start up my Q5?

If I start it up within about 15min of turning it off, the screen will stay on radio pre-sets. But if it gets left longer, when I start it up, it will be on the main radio screen with all the Sirius channels.

Is this normal behavior?

Certainly not the end of the world if I have to flip it over to pre-sets whenever I start it up, but it would be nice if it would just stay there.
