Sprite sheet with irregular shapes?

[RetrocadeNet]

Is it currently somehow possible to somehow prepare a sprite sheet/sprite atlas, with sprites of different sizes? By any I mean either manually in the gui, or by importing some kind of file.

Actually, now that I look at it, is it the case that Sprite Collection creates its own Atlas? If that's the case, then it's uber awesome!

Yes the sprite collection creates its own atlas
