Alexandra,
You can create content documents in the Sourcing Library that look just like event content and have your users pull them in when they need a section(s) for their events. You can organize in folders and they can drill in to what they are seeking. You can also add editors to the content so others can maintain the content. Lastly, you can search the library on a lot of elements, even commodity if you added such to the content document.
Check it out, I think it might be of value.
