A use case example best explains this: I have all retail/shopping sites blocked in my general web search, as I am a researcher and don't want to see those in my results. However, sometimes I do want to go shopping. So, I created a 'Shopping' Lens that contains a curated selection of the retail sites I've blocked that I want to access for that Lens.
Another use case is blocking social media results from my general search results. However, I may occasionally want to search social media sites for my research, so a custom Lens for that would be great.
These cases don't work because the 'block' is universal. I would LOVE an option in advanced Lens settings to allow sites I've specified to be unblocked for the corresponding Lens.
(I'd also like to add more than 10 sites to a Lens.)
Please see the example use cases above. Thank you!
