[Cerrado] Automatically translate product taxonomy custom fields

Background of the issue:
I am developing a site and have added custom fields to product taxonomy. These fields contain a lot of text that needs to be translated into two different languages.

Symptoms:
I don't see any option to use automatic translation for the custom fields in product taxonomy.

Questions:
Is automatic translation of product taxonomy custom fields possible with WPML?
Is manual translation the only option for translating custom fields in product taxonomy?
