Yes.  This is easy.

Yes.  I'm not familiar with that code, but it's probably not too hard
to make this change.

stop doing anything.  It only tells a recorder to start doing
something new.  This would be a whole new concept for the scheduler
and may or may not be difficult depending on what problems come from
