You can't merge them. I had two tickets like this once. Just like yours, they were purchased at two times for two reasons. When the return of the first was changed due to weather I called CO and carefully explained my problem. Since I would have missed the first flight of the second ticket because CO couldn't get me to the proper place in time they agreed to get me to my second destination. CO was entirely reasonable.
