Currently MS_DESIGNSEED workspace variable can set seed file as template when using no wizard, however that variable does not set template if you use a Wizard. Organization have different seed files that they could apply based on the project or even discipline using managed workspace though that does not work with wizard drawing creation.

Ability to set a default seed based on project or application has been a frequent request from my user base. if this could be set off of some workspace or application variable that would help speed and quality of new file setup.
