Is there a resource for stores participating in the Store championships?

FFG also has the 2020 Store Championship Event Outline.

I'm curious if we'll even get a list like we used to. I haven't seen much in the way of local stores promoting a SC. I know one got a kit eventually after being sent a wrong kit.
