No, because all routes are GPS coordinates by time. If you want to take the time, you could take the largest part of an existing route you want to use and upload it to a web site that you can create routes with. Then edit that route and add the other routes manually. When done, export from the web site and import the route into Cyclemeter. To try and modify a GPX/TCX file manually will be a bigger task than what you will want to take on.
