Additional column for drillthorugh

It would be very helpful to be able to add columns to an existing drillthrough database. Currently this is not possible. There is no control over the drillthrough database at all (only via ETL Load process). This is a pain once there are more columns for drillthrough coming along later in the project and ETL is not adding them to the database. Instead new columns will get ignored. Also the ability to remove columns as well as remove data from the drillthrough database would be very helpful. With on-prem installation this was all possible by connecting via H2 client and user sa. There was full control over the drillthrough data. Now it has become a "black box". Would be great to get the access back and gain control over the tables / columns and data.
