Welcome to the forum! My only solution for that would be to highlight all the items you wish to modify, then either mouse-pull the right or left side of one item, which will pull all the other items the same distance (left or right), or apply a fade in or fade out to one item which will fade all items the same amount.
I know this is not an automatic function, but it's the best way I know how to accomplish the task. Best of luck Shertes!
