Dashcode: How to create a custom/new Project Template?

I'm trying to customize the javascript that Dashcode uses. So that I won't step on Apple's Project Templates, I want to make a custom project template that would appear as a choice after you click "New Project." I have been able to modify one of the exi开发者_如何学运维sting templates (like, Custom, Browser, Utility, RSS, and Podcast). I can not, however, seem to add a new template to the list, like adding "JJ's Awesome New Cross Platform Template" as a choice.

I have tried copying the directory Plugins/TemplateWebCustom.wdgtTemplate and changing in Custom's Info.plist file the com.apple.Dashcode.template.web.custom to, say com.apple.Dashcode.template.web.custom2 and in Resouces/project.plist updating the key value pair: TemplateIdentifier ==>com.apple.Dashcode.template.web.custom

Is it possible to add a new Project Template? What the minimum steps?

Thanks, JJ

After a bunch of experimenting and searching, this doesn't appear possible. I could be wrong.
