Is there a way to flip multiple objects at once but retain their position on the page without having to select each one individually? For example, if I had a text box at the top and bottom of a page, selected both and then flipped them, rather than the text box at the top swapping with the one at the bottom they both stay in the same place but flip upside down?
In Illustrator, you'd have the Transform Each command to do this, but in InDesign, you have to use the Transform Again feature, which, if you are only flipping 2 objects doesn't save any steps. But, let's say you want to flip 16 objects as you describe...in place.
Select one and choose Object > Transform > Flip [Horizontal or Vertical]...
Now select the other 15 and choose Object > Transform Again > Transform Again Individually
