Add more overlay options

Hey there! I’m trying to see what it takes to add two options to the row overlay style.

Basically, I need to options (one light and one dark). When selected it would take away the ‘overlay color’ field and add a respective class to the row. Like .my-dark-overlay-row or .my-light-overlay-row for example.

The color is in the customizer and added via LESS CSS. It works fine when I add the class to the row, but I would much prefer the end users not have to add a class. Just not user friendly for the average business Joe.
