CentOS - Mar 2008 - LVM: how do I change the UUID of a LV?

I know how to change the UUID of Physical Volumes and Volume Groups, but
when I try to do the same for a Logical Volume, lvchange complains that
"--uuid" is not an option.  Here is how I've been changing the
others
(note that "--uuid" does not appear in the man pages for pvchange and
vgchange for lvm2-2.02.26-3.el5):

pvchange --uuid {pv dev}
vgchange --uuid {vg name}


Any suggestions? I'm pretty much open to any arcane/convoluted
procedure, but I refrain from copying the data to a temp place so I can
re-create the LV as that would add too much work and would kinda defeat
what I'm doing.  Thanks!
