Tagging artists individually vs. tagging groups/circles for project-specific art?

I hope my question makes sense.

Artist rice deity is part of the group FLAVOR FOLEY. They did the art for the music video for Static (Vocaloid), and have drawn some standalone art for the MV as well (e.g. post #9842002)

Do we only tag the artist and not the group?

Illustrations are generally tagged with the specific artist that drew them and not the group/circle. Artists who are part of a circle can have the circle name added to the Group section of their artist page.
