Replace all options in Representation for a main option combining view representation and positions and calling it configuration instead would save lots of time. You would no longer have to combine both tools to get different assembly configurations showing or hiding parts in different positions. You could copy a configuration and paste it to start from there to create new ones.
That way you can just have different configurations with different positions and easily hide or show components in the same tool.
That also goes for parts, where you could suppress fonctions and create different part configurations that can be changed- in assemblies.
