You can view the analytics of individual uploads as you may know, but you cannot view the stats/info of a set of items with a set tag for example.
I don't really see the need for this idea of viewing only certain types of model statistics as overall, I want to know that I'm getting sales, regardless of the models that make those sales. I am however not opposed to the idea, and I do support the OP's 'idea' as such, to have access to certain models with said tags, and their individual stats.
Hope this helped you anyways,
