One way you can already do this is by creating multiple E-mail "Form" definitions -- when there is more than one Form definition with the Form Type "E-mail", then you will be given a list to choose from when you click "E-mail Confirmation" from the Quote/Confirmation dialog.
So now you need to know how to add E-mail form definitions. You can import a sample definiton that duplicates the standard confirmation E-mail. See the documentation here:
http://campgroundmaster.com/help/formssetup.html
... and in particular read the paragraph "Making other changes to the default formats -- Importing and changing templates".
Beyond that it should mostly be a matter of going through the form definition and changing the elements as needed -- specifically, change the "Data" elements that get the text from the Settings into "Text" elements with the text you actually want to show.
