Provide a more obvious way to play multiple stacks of the same card!

The very first thing I wanted to do in my first game was put down identical stacks of the same Goal card for each of my players. So I played one stack, then went back to my hand to play the next - and the card was no longer there. After a moment of bewilderment, I picked the first one back up and duplicated it five times. Duplicating makes it say "Item name (copy)", so I then had to delete the (copy) part from each card. I played my five stacks, finished my move, and went back to the "Manage your game" page to find all the copies I'd just made cluttering up my master list of asset cards. So I deleted all but one, not realizing this would make them impossible for my players to pick up in the game.

Then I talked to someone I know who is also running a game on Storium, and he suggested I play the card and then use Add a card -> Choose from custom cards. So I tried that with the same card, and my players were able to pick up and use all of the new stacks. However, it was still a bit of an ordeal to get the cards out there in the first place, and there is no indication anywhere that that's the way to do it.

Also, one of my players mentioned having encountered in other games that if there were cards up for grabs only one stack of each kind was available per scene. So I'm guessing I'm not the only one who did it wrong without realizing.
