How to make a blueprint movement follow another blueprint

Hi. I currenty doing VR project. So currently i need to move an object. Its like you have 2 blueprint which is a bottle and one more blueprint is its cap.
Both different blueprint because need to apply something that cant be in a same blueprint.
So now, i want to make the cap move together with the bottle.
So basically cap blueprint follow the movement of the bottle blueprint.

You can attach them as actors. You can either do that in the level editor, or in blueprint.
