WP: Add codes to feeds

[Horny Joe]

I can't find where to do this....
I have some feeds on this blog, where I want to add a bannercode to each post automaticaly. I use feedwordpress and tried to add a key/value in "Syndocation->Post & Links" but that did not work. I am sure that I have seen this somewhere, sometime....

you need to download a plugin for feed and install in your wordpress .
