I have checked with the resources I know of, one being a blind consumer/technology "guru" who was unable to answer your question but offered the following. He believes it can be done with Duxbury and a braille display, but he isn't sure how. He suggested contacting Duxbury, as their tech support is very good. Duxbury may be able to help, or point you to the appropriate place in the manual that addresses your questions. Duxbury’s number is 978-692-3000. Additionally, they probably would also know of a good trainer who may be able to help with some of the more advanced stuff. It is my understanding that training can be provided remotely, so the trainer would not have to be local to you.
I hope this is helpful. I'm sorry I don't have better answers for you.
