I do alot of caching with family and friends but they started way before me so when I go caching by myself I like to try and get those caches they already have and leave the caches they dont have to those days when we need to go caching.
So I thought if a feature under the 'That (And)' where it has options such as 'I haven't found', 'I don't own', 'Is Enabled' and maybe something like "(Username) found" could exist and you would be able to have a scroll down or such that you could then choose that username and it would give you those requirements.
Giving you the caches you have not yet found but a friend of yours has and you would limit that to 500 caches still and be able to just download that onto a gps and just go...
