Is it possible to send only selected posts to RSS feed?

I am starting a new membership site where most of the posts are protected content and they will NOT be sent out via a feed (I haven’t even burned the feed yet). However, I would still like to have some selected posts (all under the category “News”) go out via RSS to stream on my social networks and to my subscribers. Is there a way to do this?

Also… I just upgraded to 2.9 on a couple of my sites and now I am reading on many of these posts that that might not have been such a good move. Hope the feed works if/when I set it up.

Thanks for your help.
