Not possible to have multi-line BMFont?

CCLabelTTF works fine for multiline, but I’d like to use bmfont (different constructor, only accepts width, not height and width)
My use case is a tutorial scene, also, the bmp font itself is a little large, I like to scale it down.
I’m guessing i have to manually scale it and calculate the width to set, so I’ll try that, but I’m open to any suggestions.
