Why not try using the Generic content module provided in the Sitefinity backend for these purposes? It provides you with a handy way of managing the content items inside the module (you can assign categories to items, perform filtering, track revision history, add custom fields etc.) as well as convenient textual input using the features of our built-in Editor. Another advantage is that you can easily create/get content items using our API. Please take a look at our Content Writer's Guide
to review the described functionality in more detail and estimate if my suggestion suits your purposes. You can also take a look at this article
from our documentation which includes code samples and explanations on how to deal with Generic content programatically.
I hope this information helps. If you need any further assistance, or the functionality you demanded differs from what I've offered you, please do not hesitate to write back.
