Resmed S9 - Change "default" off screen?

Whenever I turn off my Resmed S9 Autoset, it goes to the "humidity" screen and shows the cool down cycle. I was wondering if there was a way to change that so it displayed last night's sleep summary statistics. I know it isn't much to press the button to go to the summary screen, but it would be nice if I could change the default. I would imagine that the other S9 machines have the same behavior.

I have never heard of this type of option.

No you can not change it sorry.

That's likely in the BIOS or some other startup software loading... which brings me to another question. Is there a reason why the PR systems get/need flash updates from time to time, and has Resmed ever done that kind of thing? I think it would be very interesting to delve into those inner workings ...I should be posting this anonymously
