Additional Option Needed for AI Image Generation

My keywords and title do not describe to the AI which images are the best type of images that should be created for my specific content.

I need a 'text box option' to enter a few words that override and better describe the exact AI images I need for my specific type of content.

If I'm able to use my own words to fine-tune the AI image generator instead of the AI "guessing" from only the content and keywords, it would be 1000% more accurate at delivering exactly what I need for my specific and unique article.
