Fetch only first level of grouped rows from Excel

Question

Is there a way to fetch only the first level of grouped rows in an excel worksheet (eg. Luxury Cars, Mass Market Cars in the below data)? As the grouped rows can differ month by month and I do not have a master list of the grouped rows, I have to keep tuning the Filter tool every month.
