How do i update sheet format across multiple sheets in a drawing?

We have a lot of drawings in our library with many of the drawings containing up to 15+ sheets. Up until now to change the sheet format in a drawing i would have to right click on each sheet and update the format. This is painstakingly slow. There must be a quick way of updating the sheet format on each sheet! Help Please!
