Wanted cards for trading

I’ve been thinking about implementing per-card wanted count, it should be relatively straightforward (compared to other behaviors people want, like deck building count). My idea was to have an optional override for each card, so you could still manage all cards at once, but override specific ones. I believe that is what you want? Maybe I’ll come along to implementing this sometime, but recently been more interested in the new trade system and stuff around it.
