I just committed a change which does this.  Apply options should still 
work for everyone.  The only change is if showOldAnswers (the default 
value) is set to 1, sometimes we pretend it is set to 0.

Now by default, practice users start out with not showing saved 
answers.  This can be adjusted to everyone or no one or anything in 
between in global.conf.

I also added that no one starts out with old answers if we are past the 
due date.  So, this is somewhat hard-wired.  If this should only apply 
to some users, let me know - we just add another permission cut off to 
global.conf.
