If you have multiple data items that are pointing to the same page on your website the way to distinguish them is by adding anchors to your URI. The URI needs to be unique to each data item and in order to make them unique you can use #word at the end of the URL. 

For example, you could have www.exampleURL.com for the Organization data item, and then www.exampleURL.com/#video for the Video Object data item that is for a video that exists on that page. 

Like this:

Note: our tool typically auto-populates the URI with an anchor tag as you link new data items within an existing one.
