It sounds like that would be quite a long list. I have found observations like that while filtering for easy-to-ID taxa (for me, someone very familiar with ID of these taxa) in areas that receive a lot of attention already (such as filtering for Birds in the United States). We already have such a database when you filter your Identify to such genera/taxa. This is already what some ID experts (like me) do.
There are also events to identify species in areas that have relatively fewer observations but a relatively higher number of observations not yet out of Kingdom ID, such as Mission Impossible: Africa.
