It would be awesome to set up a CustomGPT for a brand, and then have projects within that GPT that can apply all of the knowledge from the CustomGPT setup, but apply a new job or role for a specific project within that brandGPT.
Example: GPT set up with brand docs, business goals, KPIs, ICPs, etc.
Project> Blog copywriter
Project> LinkedIn Posts
Project> SEO Specialist
.. etc.
This way it can operate as it would an agency as a coworker!
