I'd like to be able to code prompts in Firefly to easily replicate styles in prompts

Let's say I want to prompt a teen boy in green overalls and a blue baseball hat, in various scenes but I want to re-use the same character in other prompts.

Or, I want to prompt a white tiger stuffed animal drawn in cartoon style in various scenes.

In the prompt, I'd like to add a unique code, say code-char-style-25BBH or code-char-style--wtsa1

Then, reuse that style code to prompt scenes with that character, which would result in the same character from the original prompt, but in a different scene, depending on the details in the new prompt:

"code-char-style-25BBH riding a skateboard on a futuristic halfpipe"

One might prompt codes for other objects in the scene that they might like to recreate in other scenes (a box of roses = code-ROSEB115)

I don't even need to ask if it's possible, because you're up to such groundbreaking tech that I know this might be just around the corner.
