"Evidence relates to one subject" DQA and photos with multiple species in them

I disagree. I only go to help pages when things are ambiguous or confusing and I would guess most other people do the same. “Evidence related to a single subject” unambiguously refers to more than the staff want it to refer to. Because “Evidence related to a single subject” is unambiguous, there is zero context for someone to guess that it means only a subset of “Evidence related to a single subject”. That said, I see no good reason not to tag single photos as “Evidence related to a single subject”. Why make a tool that only tags a select set of observations with this issue? If they only want a subset of “Evidence related to a single subject”, they should change the name to make it accurate for what they want.
