CIS / Firewall - How to disable some url?

Hi all

I use CIS Premium 10.
Q1: How can I add a specific web page to the firewall so that access to the site is blocked and will not be visible?
CIS alerts me when i try to visit this site, will i get some notification?

Q2: Can i use (and how) some .txt, .csv datafile with the url list of potentially harmful pages, or malware links?
Or Comodo use own database to block potentially dangerous sites?

Thank you all for help and information
