When do new items get to the Rewards screen?

I have over 500 points saved up but I don’t want to waste them on a burger I don’t really want. I’m waiting for the bacon and swiss smash burger to be added to the selection but I want to know if I’ll just be waiting forever.

Also, why not add a full combo to the list? Chick-fil-a just has a generic “Meal” option that you can then fill out with what you want.
