Sometimes I want to search in the Trade Office if someone is offering things for a certain resource or item.
E.g. I do own a certain adventure 5 times. I would like to sell some of them.
So, I would like to make a filter on this adventure and see what I could get for it.
Unfortunately, the Trade Office only contains a filter on the resources you can buy.
I think an additional filter on the resources you could sell, would be a nice addition.
