47. block airfield or tank base?

Hi makers,
 
I'm used to use Command Behaviour MCU and Server Input to change what's available on an airfield while the mission is being played, for example swapping MCs for I16s :
 




 
 
However, while in the new patch changelog, one can read that "47. Mission designers can block airfield or tank base by assigning it an empty object pool via CMD_behaviour command.", I'm not quite sure what have changed :



Does anybody know?

Rather than changing "Country" to neutral to make an airfield unavailable, you can change "Float Param" to -1 instead. The airfield is shown as belonging to the current country but you cannot spawn in at it.
