Custom Filters on Webpages, Block video ads – Norton Ad Blocker Review

Great Norton product, seems to speed up Safari. However, could you add more filters in terms of blocking video ads, such as on YouTube, and pop-ups on Google. Could you make custom filters, in that you can manually select objects to block like specific adware and pop-ups on a webpage (ie. a filter blacklist), similarity to what AdGuard has. Thanks.
