What about photos with two species in it:

This observations shows Bombus affinis on Eutrochium purpureum, currently the observation is a research grade observation of Bombus affinis, and the ID for the plant is in the observation fields section. However, if I want to download the research grade observations of Eutrochium purpureum, this will not be one of them.
Is this a problem? should there be two observations, one with the plant ID and one with the insect ID? Does it matter that the plant ID can’t become RG or be integrated into the research dataset?
