Trainer Improvement/help

Trainer could have a feature to add links like

Then all the articles related to these urls or with the tags carros and esportes would be automatically marked with a red dot (unwanted article) or with the green dot.

Now its possible to mark articles titles words and authours only as wanted or unwanted,but if the trainer could detect the article tag and let the user mark that tag as wanted or unwanted would be nice.

UPDATE:
Actually that feature CATEGORIES & TAGS already exists, but doesn’t work with urls and isn’t working on https://canaltech.com.br/ but works on https://olhardigital.com.br/

Because that feature isn’t working on https://canaltech.com.br would be nice to fix that bug for that website, or even better to add a feature to let users enter manually an url/tag
