actually Andrew Lees contribute a patch for this to 2.5.0 release:

         - added: 'reopen-count' parameter to threshold gate (-ge);
                  for instance when recording vinyl/tapes, this allows
                  to automatically restart recording when a new track
                  is started [andrewl]

... this should do what you need.

Now that is unfortunately not possible with current versions. One would
need to implement a new gate variant for this...
