RSS Filtering ability

I am looking to have MailChimp RSS Newsletter integration but not just on every article we publish, but the ability to subscribe to an RSS feed filtered to just a category of articles like News, Events, etc.

Is there an ability to create a filter to RSS feeds by a CMS Collection Reference Field or some other method?
I assume using a query string after the …/rss.xml URL could do this, but I’m not certain.

I only found this request regarding this problem:

No, this is not possible. Only possible for a single collection, which is how it is currently implemented.

Ah ha. Thanks for clarifying.
Yes, @samliew, I followed the tutorial for normal RSS feeds.
Yeah, will also search the wishlist then.
