Feature request: Generating RSS feed from block

We'd love to explore the ability of creating an RSS feed based on a block or specific blocks' content, rather than keywords/section tags/etc.

This would give us more control over RSS feeds we want to use for our apps. Right now it's very difficult to curate our feeds with the best content we have on our apps.

For example, to stipulate what we want the lead story to be on our apps we have to give the story a keyword and make sure the story has the most recent start date/time compared to all other assets previously using that keyword. Sometimes we want to lead with a story that wasn't published in last hour or so.
