It is not yet configurable -- will look into for the next release/update.

@SMMNECQK I've pushed a docs update to https://django-admin-object-actions.readthedocs.io/en/0.1.6/ (at the end) to address your issue. I'd still like to make this display value more easily configurable, but that's how to do it for now.
