Just to clarify: for example, I do BioBuilders and this month is focused on people named Christopher/Christine. I only have a handful of those in my watchlist, so my next preferred option would be to work on orphaned profiles.
I could play around with the search parameters in WikiTree+ and pull up all the orphans in the Needs Bio category, which has over 16,000 profiles, and then doomscroll through a big table of search results. It's doable but takes skill, and if I'm new or don't know WikiTree+ exists, I'm out of luck.
OR, with this proposed option, I could potentially just open the Needs Bio category, which I already have bookmarked, click on "Limit to Orphans," Ctrl+F Christoper/Christine, and have results in 5 seconds.
