Bounding Box Macro - Configuration specific

Hi, I have this bounding box macro but it creates custom property under custom tab instead of configuration specific tab. 

Any way to get to create the 'PERIMETER' property in configuration specific tab?

Also, for some reason this macro creates two additional configurations 'as machined' and 'as welded'. Is there any way to remove this feature from this macro?

 

I'm using SW 2017.

 

Thank You.
