Adding a Flight "briefing" to saved flights

[J G Parker]

I recently had the delight of flighting a 23-leg tour of the appalachian mountains.  This was truly a challenge and visual candy.  These are out-of-way, small airports, nestled in valleys or high on mountaintops.  

Here's the question: I am in the process of compiling the entire set of flights, plans, and weather into a package so others can enjoy it.  (I obtained the originals from someone else, but I modified them for twin props--the Baron in particular--and the originals were poorly documented.)  I've added complete documentation (including pictures and facilities data for each of the airports, etc.) and have given the flights a folder structure (like the default flights in Pro) with complete descriptions.  However, in the default flights there is also a "briefing" that appears before the flight starts.  By snooping I find that it resides in a .brf file in the flight folder.  How does one make such a thing?  I wasn't intending to make full-fledged "adventures" but I'd be curious if there is some utility for this, or just some way to compile a breifing.  Couldn't find anything in any download archives anywhere and no information at the MS site either.
