Quote Templates V 4.0 SP2

Hi,
I'd like to be able to create Quote Word templates that users can select in version 4. I'd also like these quote templates to be configurable by the users, much like the way Style sheets work in version 5, but allow the user to select from a list of user defined formats when they decide to Export to Word.

I can create Word quotes at the moment but it involves quite a bit of coding, I'd like to be able to add Sales Header and Sales Lines as merge fields in Word to allow the users to build their own templates. I think these merge fields can be added to Codeunit 5054 easily enough.

Any tips or suggestions?
Thanks in advance.
