Custom Instructions for Generating Headings (H2/H3)

It would be useful to have an option to add custom instructions specifically for generating headings (H2/H3) that include a focus phrase.

This feature would align with SEO guidelines, ensuring that the focus phrase appears not only in the body text but also in the headings.

Currently, custom instructions work within the text but cannot be applied directly to headings. Adding a “custom instruction for outlines” option would be helpful for better SEO optimization.
