Simplify Change Filament option

Currently you have to select not only the type of filament but the color of the filament as well even for non-ams filament changes. Since this has no impact on the print itself when not using the AMS (not sure if it does even with the AMS, I don't have one), I would like to see a less cumbersome way of simply being able to select unload/load vs having to select a color and filament type.
