Word of caution with this feature, if you need to change a large amount of data (say you have a tech that leaves and you want to convert all of theirs to another technician) you have to do this one at a time. I know ST has the ability to edit Customer profiles on the backend, and they may be able to perform this as well, but it may take a while to be active.
I use the Preferred Technician field sparingly because of this. I like it, I just don't want to spend a lot of hours managing that data when something changes.
