Is it possible to subscribe to the Entire Microsoft Tech Community post feed RSS?

Is it possible to subscribe to the entire post stream that we see in here?

I know it's technically possible to subscribe to each communities and their sub communities one by one but that's so time consuming and puts them in separate feeds which is not what I want, I'm looking for the RSS feed of the front page.

if there isn't one, can you please implement it? thanks in advance.
