WordPress.com Forums ? Support Is there a way to add text automatically to syn

im using feedwordpress to syndicate content onto my blog. Im trying to find a way to add some banners on each blog post advertising other sites in my network but i am having trouble in getting anything to work.

I have tried plugins such as QuickAdsense & Adsense Now that automatically add code to your post but they do not work with feedwordpress which is pulling in posts from other sources.

I have also tried In-Post Template, which again, adds text to a post automatically. It works fine when i create a post, but posts that are pulled in from feedwordpress are untouched.

Can anyone help me find a way to add code/banner to each post old and new. And which will work with posts automatically added via feedwordpress.
