Product Configurator Ax2012

Could anyone please help me with the following problem?

Say you have a configurator model that starts with component ‘1’, that then has a subcomponent ‘2’, which then has a subcomponent ‘3’. If you have a theme of an attribute that runs throughout the model, Say that component ‘1’ has either standard or premium as an attribute. If you pick standard as the attribute for component ‘1’ how do you configure the constraint to also choose ‘standard’ as a constraint in components ‘2’ and ‘3’? Does anybody know? thanks
