Line types - Break lines?

Does anybody know a way to create a Break line type in Rhino? The sort that has a series of little zigzags in it, at intervals along the line.

That currently isn’t possible with how linetype patterns work in Rhino.
Rhino’s lines consist of repeated patterns of drawn lines, gaps, and points.
There is no provision for zigzags or text in the pattern like you would expect in an application intended for drafting like AutoCAD.
