Is it possible to render a code with add-on symbol like in this image (see page 284 of GS1 General Specifications Release 21.0.1):
Screenshot_20211229_002742

This add-on symbol is used, for example, if a book consists of several volumes. So the main EAN would be the same for all volumes, but volume 1 would have add-on symbol "01", volume 2 - "02", etc.

We are now using GNU Barcode to create such images, but we would like to move to something python-only.

It's not currently possible. Maybe rendering two separate barcodes can serve as a workaround?
