The short answer is no. Some people have fooled around with transposing the commands, but it's not worth pursuing. Have you tried some of the standard Mits discretes available for IRClone (in the MX-500 or Pronto files section)? Also, have to tried putting the Mits remote into discrete mode the way you do it with their older RPTVs? Those instructions can be found here.
