OK, I learned something new today -- thanks to you!
Although I couldn't find anything about this in the help file, it is possible to create your own user-defined templates simply by saving the supplied user-defined template file for the current compiler to a new file and editing it. For those who haven't done this, they are stored in the UES directory in a subdirectory named "projects\<your compiler>" and are named "User Defined Template.wiz".
However, it doesn't seem to allow including a subdirectory in the file path/name which doesn't already exist. And since the project wizard creates the new project file in its own new directory, there is no way to create the subdirectory in advance.
I suppose this is why I never used the project templates before...
