I mean, no. The local chapters have quite a lot of autonomy. Which is a good thing.
The DSA has a lot of factions and basically no barrier to entry. You’re going to find all types. Some of them run food distributions and scream at any passing cop. Some of them are into getting even centrist dems elected. And there’s a lot of problems with more centralized national organizing.

No, sorry. But I don’t see why you couldn’t start one if there isn’t one. Or a DSC 😃
