Mass Floor Parameters and Scheduling - "Slab" Field?

[T Nguyen]

Does anyone knows what the parameter "slab", available when scheduling Mass Floor, is refering to?
It is not editable in the schedule and don't seem to show in the Mass Floor object properties pallete either?

I have been told it is a yet to implemented feature similar to "Road" under Site.
Can anyone confirm this?
