Set items are annoying

Please for the love of god, let us change a set item into another set items either for that set or just in general a set item of that category, i have 3 pairs of halvar’s stand and 2 halvar’s pledge, that i have no use for, i only need 1 of each it is ridiculous that i cant use them for anything useful, we already have rune of ascendance, just make one but for set items. Please!
