Select an AIS_Plane or AIS_Relation object in local context?

Hi all!
Sorry for my poor English.
i add an AIS_Plane & some AIS_Relations in neutral context, but they can select in neutral context only. My question is: How can i select them in an opened local context? So i can decide to continue using these objects or write my own objects with similar propeties.Thanks for your help.
