It's actually a Poser Menu item --> Figure > Copy Morphs From...

Just be aware that it will copy ALL morphs from the character to the clothing, so if you only want specific morphs to be copied, you'll have to scroll down the dialog box that opens and deselect those you don't want to copy, or deselect the character, and then just select the few morphs you do want to copy.
