  The application of diagrammatic reasoning techniques to large-scale quantum
processes needs specific tools to describe families of diagrams of arbitrary
size. For now, large-scale diagrammatic reasoning tools in ZH-calculus come in
two flavours, !-boxes and scalable notations. This paper investigates the
interactions between the two approaches by exhibiting correspondences through
various examples from the literature, focusing on (hyper)graph states and
diagrammatic transforms. In doing so, we set up a path toward a neat and tidy
large-scale diagrammatic reasoning toolbox.
