Bundled Market Board Items for Sale

To FFXIV Dev Team:

The idea came to me when I have seen players use the Party Finder to sale craft kits to people could level their crafts from zero to fifty and or fifty to sixty. The Idea would be to combine said items, ie like all lvl 52 nin wpn, head, body, legs, hands, feet, waist, neck, ear, bracelet, rings. into 1 slot to be sold on the Market Board, so one could buy a set of items and the person could sell a set of items.

Please forgive me if this idea has already been produced, this is my 1st post using the forums and haven't searched for it. Thank you.
