Short Answer: Does not look to be easily accomplished to modify the structure dramatically. There are some export-options suggested like
org-export-plist-vars but I personally have not played with them.
Digging for the Answer:
When you call C-c C-e t, you are invoking the org-mode function
org-insert-export-options-template. I did a quick help on the function (C-h f) and didn't see any helping text or options to pass to it, so I had to look at the source of the function (M-x
Reading through the
org-insert-export-options-template function, I see that it is acquiring the text to insert via
org-get-current-options. No help on configuring it's behavior in it's description, so off to view it's source as well. There you will see the familiar full bodied paragraph of template information that is inserted into the text when you call
org-insert-export-options-template. The values populate are from various other org variables, buffer name, etc.
What I personally have done is spent some time deciding which options I'd like and copied those from other org files when I start a new one. I have also thought about using AutoInsertMode to auto-populate a new org file for me but have put it off.
