Poser does - copy morphs from.  What is truly great about it is that you no longer need to have ANY character morphs in the clothing.  You can load a figure, apply a character, turn that dial-spin into a single FBM (via dials to single morph) then use copy morphs from to inject the resulting FBM into the clothing.  Viola!  Even better, once you do that, you can go and delete all of those now unneeded morphs to make a smaller figure.  I am able to take a fully loaded V4 (292MB figure) and reduce it to 22MB.  Not important if one is doing NVIATWAS renders, but for storyboarding multiple figures in a scene, it is almost mandatory.

Good to hear! It's one of those features that is pure money in my book... 

Can you take V4 clothes and put them on a different figure as well? I love the ability to take my existing shedload of V4 stuff and put them on a more capable figure w/o a hitch.
