VR capture model

Hello, I created 3 Spheres in ParaView, use the VR function, enter the grab mode, and found the following problems:
Only one sphere can be grab at a time. How can I set up three spheres as a whole, grab any sphere, and move all three spheres together?

My environment is as follows:
ParaView version: 5.5.2(64 bit)
Qt version: 5.9.6
CMake version: 3.13.0
Compiler: VS2015
VR device: HTC vive

Thank you!
