However, PM6 (and Plus) can of course take any folder or selection and do a text export of whatever metadata fields you choose, which you can then manipulate/search/store as you need - e.g. open in Excel or Google Sheets. For some purposes, this is quite powerful and helpful. Not knowing your end goal, I don't know if you would find this helpful or not.

Edit to add: Depending on what you are doing it is also possible in some cases with some steps to make changes to that metadata and be able to re-apply that back to a set of images.
