how to add(import) one more model to existing one?

Hello friends. How to add (import) one more model to existing one? For example I have a character but modeled a low-poly version or hair in 3ds max and want to import it into zbrush as a subtool to sculpt with the character model.
Thank you.

tool>import(hair)

then

load the “main” ztool

tool>subtool>append (click the hair)

Thank you very much Goast666!
