Context file format for wizards

Hello to the blue GPT team,
Is there an estimated date for the deployment of permanent context files for wizards? It would be great to be able to provide context in the form of text and images.

It would also be a good idea to add .odt files for maximum transferability between LLM models. I've noticed that using a .docx format increases the error rate when reading.

Prompt optimizers recommend an .odt format with specific presentation rules for better reproducibility of results.
