This is from a discussion on https://discuss.kde.org/t/how-to-set-a-report-which-filters-one-1-category-having-sub-categories/7810 where the OP wants a report to include all categories which are subcategories of a specified category, including any created after the report is configured, but before it is run. Currently, in report configuration, if you add a filter for accounts (or categories) and use the shortcut to mark all subaccounts of an account, it just includes the list of subaccounts known at the time of doing the configuration. Future subaccounts added will not be included.
