Multi-Object mouse Picking

I was curious if JMonkey had a quick way to pick multiple objects in the scenegraph by dragging the mouse across the screen and after finding the appropriate rays from the start and end click positions, then finding all collisions in that area. This thread:

has instructions on generating the two rays, so I don’t need that part answered, just the multiple objects part. For example almost all strategy games have you select units this way.

Thanks for you help.
