ColorCoding for discrete knowledgebase, possible?

Hey everyone,

Unfortunately I could not find a clear answer to my question in this forum / the API Docs.
I am creating consultant reagarding a quite complex a digital product. For GPT to know the features, I created a knowledgebase that explains everything in detail: Sheer feature facts with some context. No evaluation.
In order to be an excelent consultant, I of course have to provide experience knowledge. I would like to name a feature, give context and provide the experience in red and upload the knowledgebase as a .docx.

To keep it more simple for me: Can I color code my text in the knowledgebase or do I have to give it a textual marker for now like "xp: "?

The latter is my current solution.

Thank you!
