Track line thickness mod on Montana 700

Is there any way to modify the track line thickness on the Montana 700 series?

Perhaps a percentage or a thin, med, thick option to start. 

The screen is nowhere near as bright as the 6xx series and with the use of different maps the thin track line can sometimes not even appear depending on the map used.

Have opened a feature request ( but as there is no transparency on the SDLC or on the feature request model used I file it to the round file. 

ps - yes I have seen the other threads.  squeaky wheel gets the grease. 

pps - why does editing a forum post on PC keep showing "gone offline" every few seconds on the top right of the screen?
