Post Opera user - filter request

Good Day Everyone!

Is it possible to include in future releases filter feature which enables user to filter RSS feeds by keywords, something like spam filter which tells NewsFox to put such a such news which includes such a such word in title to such a such folder??? Something like spam filter in Outlook or Opera mail. I'm long time Opera user and I'm missing this feature in NewsFox. Thank you in advance. All the best and Marry Christmas.
