Better control over the "use AI to improve your prompt" for image generation

Sometimes the "use AI to improve your prompt" for image generation might write prompts that are too long or complex for what I need.

I think a slider that adjusts how long the AI rewrite should be would be in the image generation setting sidepanel would help with controlling better results. Between 100 characters up to 1000 characters. Also having a toggle between whether the image should be a remodelled as a Vignette or a Metaphor would be tremendously useful.

Prior to Venice, I used these two prompts to rewrite my all my image prompts:

VIGNETTE

Please suggest a suitable text vignette for an image that would fit the context of the text below, describing it in detail yet concisely, use no more than 600 characters, keep the result as a single paragraph: (insert original prompt/idea here)

VISUAL METAPHOR

Please suggest a suitable visual metaphor that would fit the context of the text below, describing it in detail yet concisely, use no more than 600 characters, keep the result as a single paragraph: (insert original prompt/idea here)

I think based on these the "Use AI to enhance your prompt" button could be made more reliable per use-case.

Vignette = sort of like a in-the-moment snapshot of an actual real situation.
Metaphor = a symbolic example that conveys the idea of something, how it feels.
