In the base model, some groupings are used multiple times, and each augmentation model needs to add more schema nodes to the grouping structure. For now, we have to specify an “augment” statement for each location where the grouping is used. Such an “augment” statement is repeated many times. It would be convenient and cleaner if we could augment the grouping.
