rss-status is a read-only bridge between RSS feeds and Mastodon / OStatus applications. The intention behind is for example to subscribe to Github-Status, LatestVer or other feeds with short content (sure, blog feeds do work but they contain too much text to be usefully subscribed into a Mastodon instance) using a Mastodon account.
In order to keep the list of feeds under control currently there is no possibility to modify the list of feeds from the users side: All feeds and corresponding "account names" are defined in the feeds.yml file by the administrator of the bridge.
