I have a column that has a foldername.
When I send books to my Boox Page, they get written to folder {#taal}/{#folderop10}
this all works great, they appear under the Books folder, so using Moon Reader+ Pro I can use that structure.

These two things (folder Boos and the template) are both in the settings of the BOOX driver.

When I want to see the books on the device, I have columns In library, Title, Author, Date, Size, Collections.

Unfortunately, the Collections column is empty and now all books of all collections/series are just ordered by title name, so very difficult to check for a specific series.

There is a driveinfo.calibre and a metadata.calibre on the internal storage
I also have the Kobo utilities, but I assume they don't work on the BOOX Page.

Question: How can I add extra column for Series (and # in series) or at least fill the Collections column for the books in the BOOX Page?
