Why would you wan to do that? This eludes the dynamic GC altogether. What you're trying to do is action to a model based on the event generated. That's where Event Procedure should help. Read here about that.
Each model has an attribute called CollectionsModelNameString (0x12adb) that contains all the GC that the model is part of. You can update this attribute based on the Event you receive, using an event procedure.
Better of, create a dynamic Global Collections based on the USER_*** (0x12xx) attributes. Update the values of those attributes using Event Procedures, based on the information you receive in the events. That should result in want you're searching.
Dynamic GCs are created based only on searches of attributes of models.
