Define brand ID via API for multitemplate use

Connected to our CRM, we are calling Docusign to generate envelopes based on some templates. As we have many brands, we standardized the documents in order to use global template on which we would like to set brand when generating envelope via API.

Unfortunately, APIs don’t have any brand id parameter that we can set to generate envelopes with the correct brand, and working with 100 different templates is not possible when it comes to maintenance and update.

Is it possible to add the brandid as parameter when calling for a templated envelope generation?
