Not tried it recently, but with an older release of DNAC I added a test organization to see what it was like.
Found it extremely limited, then when I removed the org from DNAC, DNAC didn't clean itself up properly (no impact on the org itself.)
I think the latest versions of DNAC allow some basic provisioning of MR devices to assign SSID(s) defined in Dashboard, but beyond that I believe it's still very limited.
