[CE/ORD] Configuration variable that defines which workset template to use?

I am working through my client configurations commenting out things I don't want/need, and locking variables in my organization CFG so that our standards will be followed when needed.

What is the configuration variable, or variable tree, that determines which workset template is used? Everyone's template is just a little different, and I'd prefer to create my own template and use that wherever possible.

Also, is it possible to create a workset if the directory structure already exists? Our project directories are usually set up by our project managers long before billable work starts on a project. Any new worksets I create do not need to create any directories - I need only the CFG and DGNWS. I'm pretty sure this can be done but I'd like assurance from you guys.

Thank you!
