Hi,
Is it possible go move a card into tab? I have a card that I've mirrored and I want to move this mirrored card into a tab in order to draw a graph based on its data. Here's what my deck looks like:

Now when I try to drag the right window into the "Untitled Deck" tab it'll look like this:

which is not what I want. So my question is, can you drag a card INTO an existing tab? If not, is there no way in mirror a card into a tab?
