In DocuSign, there is no direct way to prevent users from creating their own document custom fields if they have the permissions to create templates. However, there are several approaches you can take to better control and standardize the use of custom fields:
Roles and Permissions:
Use DocuSign's Admin Tools to set up specific roles and permissions. While you can't specifically restrict the creation of custom fields, you can limit template creation to certain users who are trained to follow the standard procedures.
Template Management:
Centrally manage and distribute templates. Designate a group of admins or a committee responsible for creating and maintaining templates. This way, you can ensure that all templates adhere to the organization’s standards.
Custom Field Libraries:
Use Field Templates to create a library of standard fields that can be easily added to any document. Encourage or mandate the use of these standard fields instead of creating new ones.
That said, I think this would be a good enhancement that could be added to the permission profiles.
