Idea - Convert Upgrades Into Wayfarer Credits
This has probably been brought up before but since the search sucks, ima post it anyway.
How about Upgrades be converted into Wayfarer Credits instead.
Wayfarer Credits could then be used for more things. Eg. Use it as an upgrade, use it for a manual review by Niantic on a rejected Nomination, use it to get some extra Nominations.
Basically make reviewing efforts a bit more rewarding and practical.
