Certainly.  You'll have to watch the referenced slice in the canocial name
(wd0s?a), but you should be able to work it no problem.

You'll need to add your new slice to the disklabel so you have a way of
referencing it.  (ie make it wd0f or whatever is available)  I'm not sure
how to do this (disklabel -e?).  Perhaps someone with experience can jump
in and right us both.
