create a routine for making breaklines
It would be great if a routine was there to create breaklines by just clicking on existing lines and/or the same way lines are created by point number and range of point numbers. Better yet would be to have any lines in a drawing to be used as a breakline.
I think there are ways we can make this easier. If you know all the commands in MicroSurvey you can use them to accomplish the task, but there is a good reason to make it easier by adding some functionality to the MsSurface menu in the breakline area.
The breaks should be stored as simple codes so that you may use automap to generate lines in 3D. ie: we use codes x1, x2 and so on. Each x line is pre-set in the automap to join by 3D on a layer called breaklines. If the crew gets lost while coding breakline x1, they can just start a new break on another x code and run with it. We have the crew table the meanings of these code lines. x3=ditch or x15=fence or whatever. That way you can use the automap to make breaklines first and then use the "change description" to assign the code a real descriptor later.

I think you're talking about 3d breaklines used for controlling the creation of a TIN. But any 3d line can be selected as a breakline, can't it? If the system you are referring to (created by point number and range) is the "connect points by description" command, it could be that the command creates 2d lines at an elevation of zero. But you can convert any 2d line to a 3d line and then use it as a breakline.
