I think you might be missing a level. Think about the automotive
reference design system you posted the DT for a couple of days
ago. Don't you have cascaded switches, which are not members of the
same DSA tree. You might need a component for that whole group of
switches, above what you suggest here.

Can you nest components? How deep can you nest them?
