If a subassembly is moved to a different attachment point, all associated targets are lost. It would be really nice to maintain all associated targets when moving things around in my assembly.
When a corridor has dozens of regions using common subassembly (i.e. Guardrail), it is necessary to manually click through each region to set the same guardrail targets, over and over, hoping that you don't miss one. I would like to be able to batch select ALL of common subassemblies (i.e. Guardrail) in the corridor and batch set the target properties.
