Make installer able to reuse existing ZFS pools

since the upgrade from 9.2 to 10.0 didn't work out for me, I'd like to reinstall my system from scratch. Under the old unix partitioning schemes I was able to tell the installers not to touch my /home-partition, install the system, and then simply mount my old /home under the new OS.
I wasn't able to reproduce such a procedure using the pc-bsd installer in expert mode. What I'd like is an option to reuse an existing ZFS pool, and to tell the installer to leave certain datasets within this pool (e.g. /usr/home and all subdatasets) untouched. This way it's unnecessary to play back the home directory from backups and one can just install over the old installation without hassle, like it was possible to do with classic filesystem structures.
