CA - directional dangle behaviour

Hi!

If you have a photo and you want some parts from it to dangle, then you have to cut up the photo and piece together, and make some parts that you want dangable? It would be great if you could have "directional pins behaviour". Don't know what else to call it. With this I mean that I put a pin and then a direction from that pin, and then a behaviour that I want in that direction. but not in the other direction. For added detail if you don't want a straigt line you could pair it by drawing a short border/cutting line, if you want fine detail control.

That would be usable if you would make like the "ikea pillow monster" that some user had done in an Okai Samurai video. Instead of lots of Photoshop piecing you could just use this.

Thanks!
