Filtering on a Deck? (Like context, but with a static value?)

Questions

I know you can set sub-decks to have context based on the context of the deck they are inside of, but can you set context based on a more static filter?

For example, currently I can set a sub-decks context by SubDeck Field A = ParentDeck Field B

Can I set context like this instead? SubDeck Field A = “Blue”

I can’t seem to find a way to do this. It would be very helpful if this were possible.

Thank you!

I figured out a way to do this. It’s a little strange, but creating formula fields that simply equal a static Text string on my models seems to work.

So on ParentDeck I create a field called Blue with the value “Blue” and then for context do
SubDeck Field A = ParentDeck Field Blue
