3ds Max :: Remove Unnecessary Vertices Of The Same Plane?

For example a normal cube requires minimum 8 vertices but of course there may be several width, height and length segments which increase the amount of vertices. If there are more than 8 vertices I would like to remove or combine them since for a single plane only 3 (triangle) or 4 (rectangle) vertices are required. On the other hand, I do not want to optimize anything else and this operation should be automatic (thus optimize and pro optimize are not perfect solutions).
