Waypoint colors feature has specific origin from a former discussion:
Change waypoint colors / symbols globally has meaning for one specific platform.
It is like route colors in app. It must not be transferable, but stored in web settings.
So if all mean waypoint colors globally, you can continue discussion for website.
That is if users want for the website to choose among symbols for all waypoints.
App will not support global symbol changes, I could only think as discussed here.
