How to do object space bounding in ss6, so that all elements in space and be separated in Datagroup property.

Hi All,

I working on one big project. it has many phases. My engineer wants all elements as per different phases. 

I created the Space model and now I want to do elements bounding so that we can add new Datagroup property like Space Name to all elements as per there spaces.

Which helps us to quantify the elements as per phases. I also tried to find a solution in GC, But I cant find it.

In Solibri model checker we can categorize elements as per Spaces.

I have many discipline models. if I will do manually, it will take a long time. and if we can use any automated process so that will be helpful. 

Or is there any way so that I can edit DataGroup property selected elements ( wall, slab, beam, ....)..
