Playing a group by default

Can a group I’ve created play by default?

I have created a group called “Downstairs” pairing my living room and kitchen speakers.

I’ve got a Beam and two One SL speakers in my living room and an IKEA SYMFONISK Bookshelf in my kitchen.

When I watch TV, I’d like my living room and kitchen setup to play by default without me having to add them manually every time.

This is very cumbersome
