How do I change gravity within a volume?

Greetings!
Another question for this awesome community!
Back in UDK there was a thing called “Gravity Volume” I believe, enabling us to change the gravity on the Z axis of all things inside the Volume. Now in today’s awesome Unreal Engine 4, I can only find what’s called, a “Physics Volume”. I’ve been spending some time trying to figure out how to invert gravity with such a Volume, however, I have failed many times, that is why I have come here, in need of your assistance to crack this case!
I wish you all the very best!

Would be interested to know this too.
