Installing Transparency Flattener Preset for Indesign Server CS4

I'm trying to figure out how to install a transparency flattener preset for InDesign Server CS4.

I can see how they are installed for the InDesign app.  Edit -> Transparency Flattener Presets...

But I'm not sure which directory to install these on for the server.

I've seen a post that mentions:

C:\Documents and Settings\<UserName>\Application Data\Adobe\InDesign\Version 6.0\en_US\Transparency Flattener Presets

/Users/<UserName>/Library/Preferences/Adobe InDesign/Version 6.0/en_US/Transparency Flattener Presets

for the Desktop version.  But when I place files here even for the CS4 Desktop, they don't seem to show up in the UI.

Any help would be appreciated,

Thanks,

Dennis
