Suppose you had an LLM (NN) producing its default output from an input (a generally optimal for-most-cases role-sys, and any role-user), and then you wanted to have that output reformatted in some style (e.g. "In iambic pentameter" | "haiku" | "eli5" | "in the style of Feynman" | "bulleted like Axios" ...). How would you keep the internal NN workings that were basis for the original output, and use them to get a rewritten version (instead of placing the original query and output in the context and ask to rewrite it)?

In other words, is there a way to keep the internal process intact up to the point of the formulation - and have only that vary.
