In Anaplan Classic, in the old modules view, there is the column "Used in Dashboards" which informs of all classic dashboards using each module. This same concept is needed within the New Module View for New UX Pages, so that model builders can quickly identify all NUX Pages using a module.
I know that the opposite is available within the "Pages" tab, where you can select a NUX Page and view a list of modules being used by that Page, but this way of getting to the information is significantly less helpful than the above, where it is available by module, particularly when attempting to identify stale modules.
