Hey @dadim
For the physics properties, I don’t think you can change them all at the same time, unless multiple objects are using the same particle system.
If you are using the animation option on the modifier, the little dot to the right of the setting, this will also give you a keyframe in the timeline, and you would of moved this along with the others.
I’m curious to know how many objects you have with modifiers with a time setting?
Any objects with the same modifier, you can select all the objects and hold ALT will changing the setting, this will change all the setting on the same modifiers on all selected objects.
Hope this helps a little.
