Setting HTML signature in Zimbra Desktop 2.0

[fantomxr]

Hi all,

My company has decided to go for a uniform signature style. I wrote a script that, in short, generates a HTML signature for each user and spits it into zimbraPrefMailSignatureHTML. A couple of our users prefer Zimbra Desktop, however (with which I'm totally unfamiliar). Is there an equivalent way of directly entering signature information on a Mac running Zimbra Desktop 2.0? I can't just paste the HTML in the UI as I'd hoped.

Thanks in advance.
