ARAM Champ Select

Can we have a button or something where we don't want trade invites? If I get something I like and don't want to trade it, I don't want all 4 teammates asking for it. This also happens when X player attempts to trade, I politely decline trade only to get another trade offer from the same player after they trade another player or use a reroll. It's really annoying getting multiple invites when you don't want to trade. Maybe they get a champ you like even better so maybe YOU want to initiate the trade but yeah, please make a "ignore trade invite" option.
