Custom Cargo for map?

I building a game map for my friend’s server and I stuck on one thing.
How can I add a custom cargo shuttle for my map only?

I already know how to create and save shuttle templates, found list of all avilable cargo shuttles in prototypes folder, and I know how to replace emergency shuttle in map proto.
But thers no thing as Cargo shuttle definer in map files. How can I pick the shuttle that I need on map?
Is there even a solution that don’t need rewriting half of game?
