Editing trust_level groups

Personally I would really like if I could display flair via the automatic group.
I am attempting to use Trust Level Avatar Flair Theme Component and but it requires me making icons and not having the font awesome + colors option. It has been asked if the theme component is even needed now that you can edit some of the trust_level stuff like flair but can’t set them as active group.
Some sort of functionality, even if it is just to show trust level/automatic group flair when no primary group flair is set would be great as a core feature. I don’t want only group and staff to have flair and trust flair would be a great way to do that.
