I'm also on the same boat. Couldn't find a oneclick solution...
After hours of going through this forum I ended up doing it this way:
- Just make one project, and select all chains "multisession"
- After indexing is done, you should get something like the below screenshot

- doubleclick each one, and configure individually, DEFER after each configure
- when all has been configured.... "process all sessions"
Would be nice to be able to set a single quality level for all in one shot (I always use ~1000-1300kbits/s , sse @ highest quality, .2-.3 bits/pixel, 128mp3 or ac3 nothing inbetween)
Be EVEN nicer if there was an option to have them automatically combined into one avi+sub at the end...
