Adjusting group defaults helps determine the criteria and baselines that groups open with when you go to set them up.
Auto Group Defaults
Default Spaceout: allows you to set the value and increment type of the calculated difference between listings in an Auto Group
Auto push prices: determine if you would like to automatically push prices for the entire group
Apply Ceiling to Group: toggling this determines whether the ceiling you place on the group applies just to the anchor (if off) or to the whole group (if on)
Base Group Defaults
Auto Base/Base Price: determines whether you would like your base to automatically calculate a base price. If this is set off, you will have to enter a dollar amount to use as the manual base.
