The problem of identifying suitable view-update strategies is typically addressed in the context of a single view. However, it is often the case that several views must co-exist; the challenge is then to find strategies which allow one view to be updated without affecting the other. The classical constant-complement strategy can provide a solution to this problem; however, both the context and the admissible updates are quite limited. In this work, the updates which are possible within this classical approach are extended substantially via a technique which considers only the states which are reachable from a given initial configuration. The results furthermore do not depend upon complementation, and thus are readily extensible to settings involving more than two views.
