Can you Please do 2 things for Howling Abyss Keys?

1. Name them Howling Abyss and Howling Abyss Greater. So you don't have to carry both into the instance with you.
2. Make them stack. So they can count as 1. Rather than the number x (you can get 'x' amount if you forget to take your key into the instance - since going in and out can count as 1 entry).
