Hi Luke! Welcome and thanks for the feedback. This category is for feedback about the forum, rather than iNaturalist itself. You can propose a feature request in that specific category. However, in this case refining the suggestions that computer vision gives has already been proposed and the iNat team is working on it:

There is an open conversation too if you want to join in there:
