Expanded transmog "sets" tab?

there’s so many sets that get a full on “set” in that tab, like the civilian clothes, the questing green set, etc. can we please get that sort of treatment retroactively done for older armor? it’d be really nice to have all the old sets listed out, so we can see what we have and what we need, without the need for yet more addons. i love that feeling of completing a new full set!
