Is it possible, when using the "Hide Ends" option for tangent lines, to control the amount that is hidden?

Specifically, I'd like to hide a fixed length of line (e.g. 1mm) at the end of every tangent edge on my drawing.  SW's standard behaviour (at least on my installation) is to hide a portion which is proportional to the length of the tangent edge, as can be seen in the attached image.
