Add a Prologue Option to Each Chapter

I would really like the option to add a prologue to certain chapters. Occasionally the chapter either needs an opening introduction that isn't the contact speaking to me OR contains some text that the contact needs to say BEFORE I accept the mission. Breaking it out into a separate section would help so much vs trying to jam it into the top of the mission intro.

How I envision it working:
1) An additional 1000 character prologue edit box is added to each chapter in the editor. (optional text)
2) Also, in the editor, a single line "Prologue Next" text box that contains the link text at the bottom of the prologue page.
2) If you add text to the prologue, playing the game will show the screens in the following sequence:
A) Prologue ( with the "Next" link at the bottom ).
B) Mission intro ( as it currently does, with the "Accept" link at the bottom )
C) Mission Sendoff ( as it currently does )
