Adding RSS logo to syndicated posts

I would like to add some indicator that the RSS posts are syndicated and not generated by my blog. Is there a way to somehow attribute the rss feed posts with custom text like “from X blog” I would also love to insert the rss logo so it’s very clear that these posts are not original but are aggregated from another source. Is this possible.
