"Keep awake" should have an option to disable itself automatically after manually initiated sleep

I guess the title says it all - I quite often have the problem that I forgot to disable "keep awake" and this would neatly be solved by having it deactivated automatically. I know that there's already a time option but this still might be a nice addition.

Do you mean that you wanna manually input after x min deactivate keep awake?

A manually configurable timer would be an alternative but better would simply be an option, which disables "keep awake" automatically after the computer has been put to sleep manually.
