1Password 8 / Duplicate to other vault with alt-key

In 1Password 7 I was able to duplicate items to a second vault by dragging onto the target vault while holding down the alt key. This would, without any need for further interaction, duplicate the item into the other vault. In 1Password 8 it seems like the only way to do the same is by right-clicking, selecting "duplicate" and then selecting the target vault. Am I missing something, did you change the key? If the feature went away please see this post as a request to add it again as 1Password 8's current behaviour really slows me down in my everyday work where there's unfortunately quite often the need to quickly duplicate items to other vaults.
