I've already got enough companions that when I'm assigning them I'm sometimes like ooh, I know a good match for this dog, who do I have the one I already own attached to?
Currently my work around is going to hunting to see the list of wolves and attached companions there. But I would very much like an easier or more intended way to see this- preferably I would like to be able to click on a companion on the companion page and see what wolves I have mine attached to.
An icon for companions you have attached to at least one wolf like the "new" icon for ones you don't yet own has already been suggested, but that too. On companion page some kind of indication of this would be very nice too.
