Negative, no individual adjustment.  However there is new "Reset Dead Miner" option that you can set the time limit to restart if it hasn't submitted any shares.  Or you can set it to "Never".

Hashing so far with 7 miners @ 800 frequency for an hour with no restarts. 3 of my dc power leads were faulty, one just didn't work and the other 2 had detectable resistance between the positive and ground so I didn't use them, the others didn't see any resistance, so I deemed them working.

Not sure why some cables had resistance between the + and - they still worked but I didn't trust.  Could be another reason why someone has one or two lazy miners?
