Possible to have the suggested line without braking?

I recently purchased the Steam version of Forza Motorsport specifically so i could use it to practice driving my local track for an upcoming track day. I usually play racing games with the suggested line turned off, but in this particular case i would like to know what the ideal line is so that i can practice driving that line. However, i DON'T want the line to change color to indicate braking points, as i want to actually learn the braking points rather than just reacting to the line color. Does anyone know of a mod or a .ini file tweak that will make the line stay solid blue rather than change colors?
