Jog wheel sensitivity

Since my controller doesn't seem to have a button for the "seek" option, and searching the song with the jog wheel is somewhat slow (and when I mix in clubs I want to touch the computer as less as possible) - is there a way of making the jog wheel respond more? Maybe a parameter to play with? (of course something that can be changed back easily afterward to return to the normal mixing mode). I have a DDJ-SB.
