Have you ever thought about implementing company routes for the FMC?
So, I think I may have misunderstood your original post.
After re-reading this I believe you’re referring to a database of company routes to be used by the FLIGHT PLANNING SYSTEM (PFPX) for planning and subsequent export for FMC uplink.
Real world FMC’s just don’t have the memory to store thousands of routes and are typically uplinked during preflight.
Our real world flight planning system DOES contain stored routes between all of our domestic city pairs, some pairs more than others. So in that context, YES, I have thought about a MidCon company route database for PFPX, but as of now haven’t really started putting anything together.
