I try to write an add-in that associate references to a DWG file. With the interface IEdmEnumeratorCustomReference6 is possible to create these references and set the quantity for each references present in the parent file. Is it possible to create references associated to determinated configuration like in Solidworks file (i.e. i want to associated "Ref1" and "Ref2" to configuration called "Layout1" and "Ref1" and "Ref3" to configuration called "Layout2")?
