Skeleton Editor, add a reference static mesh to pose against?

I’m trying to pose a skeletal mesh for an animation sequence frame to use in a motion blend. I’m just making the character’s hand wrap around a bottle from the ichiban region of Japan. In the skeleton editor when I’m adjusting the bones, I need a reference mesh of a bottle, so that when I adjust the finger bones they will precisely grasp it. How can I see an additional static mesh in the skeleton editor in order to adjust the skeleton in relation to it?
