bt /x will do what you want.
How will it help with all those backtraces generated and sent by users to bugzilla? Or those intermittent crashes which are very hard to reproduce? Is there any reason to spend any time again if all required information is already there in appropriate and ready to use/easy to understand format?
if it's information sent by user (in any form), you can always write a small script to do the job (and also extend, message number, styles...) A+
