With Stoke City to follow in the Carling Cup next Tuesday, Mark Robins' squad have a distraction from their league progress and will be hoping to reach the second round for the first time in six years.
On the field Robins has no fresh injury concerns after Nick Fenton came through midweek unscathed after suffering a bruised foot against Wycombe, striker Reuben Reid is still rated doubtful with ligament damage.
Richie Barker is available again after being cup-tied against Leicester while Ian Sharps makes his 100th appearance in a Millers shirt.
Junior Mendes remains sidelined due to a niggling groin problem but Anthony Charles should return to the defence having missed their defeat at Morecambe.
Waddock told Shots online: "Mark Robins has done a tremendous job there and they have obviously galvanised a "pull together" attitude due to their circumstances. They will have a lot of confidence but from our point of view we have experienced some cup success of our own at Aldershot.
"Everybody wants to do well in the FA Cup and it is a competition that I always have and always will hold right up there. It is a great competition.
"You can play top teams as you progress and you always want to compete against better clubs and against better managers and coaches. Before we can think about anything else though we have to focus on Saturday. We all have dreams and dreams can come true."
