Hi djdave972
You can make a route in
free roam and of cause, your own missions in the
mission editor.
Unfortunately, no ECDIS programs can work with SS08. The SS06 pro-version had a ECDIS interface, but it only transmitted a limited set of data and there was no two-way communication, so you couldn't make a route in the ECDIS and then sail the route in SS. However the SS09 pro-version may support that function, we don't really know yet.
