Freeze column with dates, creating a time schedule

I am currently outlining a syllabus with a time schedule and now I am wondering: Is it possible to “freeze” a column with dates, so that I can move up and down lines but the dates columns stays in the order it is?

(Background: I have 14 time slots in that course, and now I am moving up and down topics, but can’t find a way to leave the dates in the desired order.)
