You're right. I've tried it with other hair props and I do see the button. And it does work fine. Good to know.

Thanks everybody.

There are some extra hoops to jump through, as noted by 4u2ges, to get the hair onto an animal prop in CC3 and then attached to the animal head bone in iC7. Especially with this particular hair. Not all the steps will appear in the UI of the Modify panel in CC3 as you would expect, but the process does work, and you can confirm in the Scene Manager. See my method here. Once in iClone, the Modify panel will show what is expected.
