Automatically update Custom GPT's instructions via conversation?

When using the official editor: https://chatgpt.com/gpts/editor we can have a dialog about what the custom GPT should do, and it will automatically update the “Instructions” for the custom GPT configuration.

If we already have created a custom GPT, is there a way that we can similarly have its prompt updated just via the conversation interface, that is, tell the GPT how it should update its prompt, and it will update its own instructions directly? (for security reason, assuming we are the owner/developer of this GPT)

No. Any changes to the GPT must be done through the builder interface.

Thanks for the prompt response. If possible, please take this as a feature request, I can see that it could offer great value for iterative improvements of custom GPTs.
