Currently, to link a matter beamer with a spawner, you need to first right click the matter beamer, then right click the spawner to make the connection. This is not very convenience when try to connect a lot of beamers to a single spawner, and is worse if there is a wall or something between the beamers and the spawner.

I think we could add a function to focus mode wrench, by first register the spawner to the wrench, it could link every beamer by a single click. This would be very helpful to build a fast and automatically balanced structure.
