There a couple of ways of doing it. If you can put all those 100 volumes in a group, then you can use the method that you mentioned below. At the bottom right corner of the page on the left hand side of the update button you would find "Apply settings to " by default it would show this volume.
If the volume is part of a group you can find a drop down that says this group, by which you can do it at one shot for all the 100 + volumes.
The other way is to use the dfm cli and script it using perl or batch or powershell which ever you are comfortable with.
