Can we have more Wayfarer challenges?

More specifically, could we have Wayfarer challenges every other week that aide the most backlogged areas, and could we have something like a passport badge for doing so that accrues stamps for every area someone chooses to help out by joining the challenge?

I think most complaints about slow turnaround come from people near cities in North America and Europe.
But Niantic sees this problem as big regions with few waypoints - so our challenges have been India, Russia, Brazil, and Poland.
So first, we need to convince them that it's a problem (bad business, and just plain mean) for someone in a suburb of Boston, Atlanta, London, or Munich to have to wait a year for their nomination to resolve.
THEN we can have a nice rotation of challenge locations - especially if the place changes every week or two, as you proposed.
Heck, just let us change our bonus reviewing area and run our own challenges. We could do it as a community and leave Naintic out of it if we could change our bonus area monthly!
YES! The only time I review nowadays is every Sunday with some fellow german friends I've met through Wayfarer. Other than that...it isn't the same anymore. Events in PoGO sometimes motivate me to play a little more than usual, it would be the same with events in Wayfarer. Please don't encourage FOMO, but I would totally love challenges. See the stats what I have achieved in the challenges, see what the community achieved in the challenges. Let us change the bonus locations every other month and let us help out areas that have huge backlogs or not enough reviewers. Just do something, please
