Can I exclude a section from an RSS feed?

I have a website with three different sections. In every section’s _index.xml I have set generate_feeds = true, which means I get the following rss feeds:

http://site/rss.xml <- contains all posts from all sections
http://site/section1/rss.xml <- contains posts from only section1
http://site/section2/rss.xml <- contains posts from only section2
http://site/section3/rss.xml <- contains posts from only section3

How can I exclude the posts from one of the sections from the main feed? I can’t seem to figure it out. If I filter out section1 from the rss.xml template, they also get filtered out in section1/rss.xml, which is not what I want.

Alternatively I would also be happy if I could have different RSS templates for the different sections so I can control what exactly ends up in each one. Is this possible?

I don’t think there’s a built in way. But! You could override the built in template and add your own filtering

Thanks for the response! But I mentioned it in my original question, I have that template, but if I filter a section out, it gets filtered out in every feed because the template gets applied to every feed that is created.

Hence, part 2 of my question - can I have different templates for different feeds?

Oh whoops! Sorry I don’t know about that
