How to manage multiple f-curve modifiers I have more than 30 bones animated and each of them needs the "cycles" f-curve-modifier to continue animating up until frame 100.

Is there any way to change all these modifiers simultaneously, or do I need to go trough each modifier separately in order to change their end frames?
If I'm understanding the question correctly, you should be able to apply the modifier to one curve, copy it, select all of the curves, and then paste.
