Possible to have a tween for a camera moving from one position to another?

I have a camera that I would like to be able to orbit around a mesh when I click and hold a button. I have that working, but is there a way to have to animate back it it’s original position once you let go of the button? Ideally I would like a nice smooth transition.

Thanks.

Lerp node you can set blend weight to multiply against a curve. Lerp from current position to goal position. Check out itween.

I remember iTween from Unity. Thanks for the suggestions.

iTween is in UE4.
