[CA] Scroll Speed vs Boat Speed

[gmckenzie]

You never really answered my follow up question below from Oct.

My question is if you might consider adding the option to add a button to the side imaging screen where you could access the screen speed directly vs going into multiple menu's to get there.

For anyone who really utilizes the side imaging to it's max, this is a critical adjustment to get good images, matching the screen speed to the boat speed.
