Using a find one showing rule with duplicate checking turned off might
work.  Using a single record or override record for future showing
that appears in the guide will work.  If you don't mind changing the
database directly, you can set recorded.duplicate to 0.

Yes.

Perhaps.  You could also add a menu item only available from the watch
recording screen to clear recorded.duplicate.
