How to trade on consoles?

Please GGG create a way for players to buy and sell their stuff even if they are offline.

I have plenty of gear to sell but I can't be online all the time to sell my stuff and progress through the game with better gear I'd then be able to buy from the proceeds I'd get.

It seems obvious to create such a marketplace where you can let your things being sold even when you're offline, and when you log in, you'll get notifications of the stuff you sold (just like the currency exchange works).

I've seen such marketplaces in other games, and despite not being easy to make, I think it would be a HUGE improvement to POE.
