Proxxon doesn't list one available for it, I don't know if you can adapt another one to it. I know for a metric lead screw there are different dials and for cutting imperial threads you need to leave the leadscrew engagled all the time anyway.
For this job you'll need to keep it engaged, but when it comes to the end of the cut you can turn it off and let it coast since there won't be anything in the way. Then you can kist turn the chuck to move it back to the beginning. At 11 /12 or 12 TPI, turning the chuck by hand will still move the carriage pretty fast.
