[Zope] Can't change title of a common instance property sheet

[Jeff Sasmor]

I suppose this is some sort of lack in the Zope management UI, but
maybe someone else knows how to do this:

If you create a ZClass property sheet you can pick an ID and a title.

But you don't seem to be able to EDIT the title of the property
sheet ever again.

Is there some magic property sheet property name or
is there just no way to edit the title from the management 
interface?

The other bizzare thing is that you can export a property sheet,
but there seems no obvious way to import one anywhere.
Anyone have a clue on this?  What's it there for?

TIA
