I will be away from the computer after sunday morning for just a day.

I don't usually set lineups in advance so I don't have a good working knowledge of the set up.

On Sunday morning, can I set sunday's lineup and still be able to set Monday and Tuesday, as well, without screwing up the Sunday lineup?

Yes Ray, you can set future lineups without effecting your current lineup. I haven't done it myself (this season), but some others have used it. Maybe they will chime in to this?

BTW, As well as your team is doing I don't think it matters who you have in your lineup anyway! LOL
