Rather than one set of custom instructions, I would like to be able to create multiple versions for different use cases to work more efficiently. And being able to toggle multiple of those custom instructions on the fly within the GPT would further streamline my workflows.
For example if I want the GPT to speak to me in a certain style and format responses a specific way, I could make a set of instructions for each (without the need to keep typing it out every time I start a new chat). Then I could toggle one, both, or none of those instructions as needed.
