Custom Feed Show/Hide RSS Censor Filter

Brief: Admin level Show/Hide option for our MRSS feed that filters what is shown. This is a "censorship" type function for an existing feed. Existing functions are built with simplepie and php. We need: [login to view URL] that allows a user to select from 7 feeds we are generating. They are all php files - ie [login to view URL],[login to view URL], etc [login to view URL] they select one of the feeds, a page to preview the content of selected category in table list with dropdown to "Hide" or "Show" that content [login to view URL] the changes will restrict the selected content from showing in the feed. Further explanation is a "filter" must be placed to make the feed not show what user selected "Hide" on. The only alteration to the original 7 php files would be a function that refers to what is supposed to be hidden and simply not showing it.
