If a user wanted to raise the same change proposal against a number of objects, all the objects can be included in one change proposal, called a multiple change proposal. The objects that the change proposal applies to are listed in the review window. If you approve a multiple change proposal, the change is applied to all the objects.
When you review change proposals, you might be able to edit the change proposal. Access depends on how the change proposal system has been set up. If you want to be able to edit change proposals during the review process, contact the change proposal manager.
