Even in 2025, this feature is still missing. That would be extremely helpful! The only problem I can see with something like this is that the X and Z values should not be automatically applied to every building, as they may go outside the building's area (Y-value for most things shouldn't be an issue, but it is if it has a helicopter pad for example). However, I CAN see something like I originally interpreted this as: edit a building's spawn points, press the button to Apply to all buildings of this type, and have all the new building that are spawned/placed automatically inherit those locations; to be honest, I thought all this time the mod automatically did this, but today I learned it doesn't.
