PD (or range) currently interviewing at each field office - where to find this info?

[MA031993]

Is this information aggregated anywhere? I have seen people mention this in posts.
Specifically interested in the San Jose field office. My PD 12/11/2019 and I'd like to get an idea about whether my interview will be soon or still several months out

greencardly dot com has some of this info
