It's not available yet in version 15 nor 16. We are currently working on it, but we don't have a release date yet. 

The temporary solutions that we can offer are: 

 - Using "Auditoría de datos" (Accounting app -> Reports -> Auditoría de datos). We can select there the accounting journals, time periods and analytic accounts that we want to export. It will generate a .pdf file. 

 - Using a 3rd party app, which may imply using Odoo.sh.
