Thanks for your reply.

With MPT selected, the CM does not generate spot start percentages, ...You have to manually put in spot percentages either way. 

  
Have you tried generating a CM with "match playing time"?  It should generate percentages for bench players, though they are not perfect.  Also, keep in mind this option ONLY affects the generation of the manager profile, NOT the selection of lineups for a single game.
