Hi Elizabeth Munsey,
You can crate a metakey where you can store the website name. You can also return a content item provider programmatically. Below is a sample code.
|ContentManager cntManager = new ContentManager("News");
|IContent cnt = cntManager.GetContent("FACA0024-19F3-40b0-A51E-CCA221A511E") as IContent;
Let us know if there is anything else that we can do for you.
