When subcategory budgets are set (e.g., Restaurants, Fast Food, Coffee Shops under Food & Dining), the parent category budget total should automatically reflect the sum of its subcategories – and stay in sync whenever a subcategory amount is updated. Currently, the parent category budget is a separate, manually-set value that does not roll up from subcategories, requiring users to manually recalculate and update the parent total whenever they adjust a subcategory. An auto-calculated rollup would keep budgets accurate without manual effort.
