It's two states, anon. The only way to make it one would be one state with normalized time, which isn't what normalized time is supposed to be used for.

You can tie multiple toggles to the same parameter and layer, but it's too messy to be worth it as long as you have parameter slots to spare. You'll have multiple toggle buttons controling the same parameter, or you have to have a different button controling every combination of toggles because each layer can only play one animation at once.
