Feature Request: Disconnected Polylines in an XYZ file

[Kookaburra]

It would be great if there was a way to specify multiple, disconnected polylines in a single ASCII XYZ file. Right now, for example, if I put the following points in an XYZ file, and open it in Transdem using "Open Route", it creates one contiguous polyline that looks like an "N":

627100.00000 4085900.00000 0.00000
627100.00000 4085100.00000 0.00000
627300.00000 4085900.00000 0.00000
627300.00000 4085100.00000 0.00000

I don't see a way to create multiple, disconnected polylines in a single XYZ file. For example, something like the following might be used to create two disconnected polylines:

627100.00000 4085900.00000 0.00000
627100.00000 4085100.00000 0.00000
break
627300.00000 4085900.00000 0.00000
627300.00000 4085100.00000 0.00000
