Editing coach/team records, salaries, etc.

Is it possible to edit things like your coaches' salaries or to add some history to your coach (like an existing W-L record). I'd like to continue an old, old dynasty that I started with another game way back in the day, bringing back the coach for his 31st season. I'd love to be able to input his W-L record, the fact that he's already won four NCAA titles, etc. Is there a way to do that in commissioner mode or something?
Second question: Is it possible to edit the terms of a coach's contract? I had another idea for a dynasty play-through where I am a young coach who gets a head job unexpectedly right before the season starts, and the AD basically gives him an interim tag for one year. The game officially gave me a 3-year deal for 80K a year when I started my new association. Is there a way to change that to one year for 80K. The challenge being to see if I can get the interim tag removed -- or if not, where the game takes my coach from there...
Thanks for the help.
(Also, is there a way to stop the world for a day or two just so I can focus on playing this game for long hours at a time?)
