Guild Wars 2

Hey guys,
So I have a somewhat simple question that I’m not sure on. So lets say I have 4 Black Lion Chests and want to send 2 of them to my friend, how do I send only 2? Whenever I try sending something, it sends my full lot of things (EX. the 4 chests when I only want to send 2). I’m just confused, please help if you know.
Thanks for any help.

Holding ALT+ dragging the boxes to the mail you should be able to choose number to send

Bumping this please respond

Thank you very much!
