Can you clarify your request? At the moment I believe your best bet to be further research on the matter. In history, there have been many forms of text-based steganography. Some of them involved aligning the text in certain ways or using specific locations for misspellings or even adopting a policy of single-letter-per-sentence filtration. There have been many methods but at the moment, not clearly understanding what you're seeking, I can only recommend further research. I would suggest looking into the history of steganography as it is truly quite interesting and may likely bring you to a solution for your specific needs. Perhaps you may even determine that a custom solution would be preferable, in which case, I would invite you to share with the community.
