there is nothing that i’m aware of in the standard iNat web pages that will allow you to get this kind of information. however, it may be possible to get this information via the API. for example, just extending an item from Make Umbrella project dashboard style available for collection projects - Feature Requests - iNaturalist Community Forum, you could see how many observations you have for each component of the sc-state-parks project by just adding one extra parameter:
