the computer does do the insertion but CRS is manipulated to do it the way the company's wants so they can stand back and say it was not manual, you will find more top bid rosters effected by this, about 2 years ago there was a small group of pilots( strong union back ground as well as experience with bidding) were working the system to their advantage ( read O/T ), AAR found out and the rest is what we have now, Thanks boys
