Enhancement - Time Restrictions - Give locking computer the same status as logged out

I have been only running your product for a short time and think its great but would like to make a suggestion regarding time restrictions.  Would it be possible to give "Locking" the computer the same status as being logged out so that my children don't have to keep logging on and off all the time?  This would mean that their time allocation does not count down when the computer is locked since they are not using it anyway.

 

Thanks.
