While I can assign X=0 (for instance) to the "group" with all elements at the left hand side of the group then being as well x=0, this does not work with Y. I like to move a group such that the "member of the group" which are the upper most members are exactly at a specific value y (e.g. y = 120). When chosing y=120 for the group, the upper most member would be assigned y= 121.99 (or the like).
