Where is the options settings or configurations for Exploded View Sketch Lines?

The problem I am having is on a stepped or off-set explode trace line.

The trace line creates nearly perfectly except the length of the start and end lines seems to have some sort of a system default minimum length.

I can click-n-drag and stretch them out longer, but I need them to be shorter than what the system creates them at.

There must be some system controlled minimum length, where do I find this length setting or how can I change it?

Please see the attached screen shot.
