LVM: pvcreate by uuid or non "dev/sdX" method

Is it possible to pvcreate a pv by any more unique means than the standard "/dev/sdX"? The reason is the external multiple hard drive dock and dev mapper on my system don't always assign the same "/dev/sdX" at boot. I work around this with ext4 mounts in fstab by mounting by uuid, otherwise the results could be disastrous reads/writes to the wrong disk.
