Currently, the only way to add multiple participants to an existing assembly-level cuts is to add them one-by-one. This causes it to update the assembly (and the cut) for each component you add. Alternatively, you can delete & re-create the cut in order to automatically add new participants. When the number of affected components is extremely large, either process can take many hours. I would like to have an option to automatically update the participant list according to the extrusion envelope (as though it was being re-created). This would be similar to the functionality that exists in Creo, SolidWorks, etc..
