Hey Krekel357,
first - sorry for my bad english but iam from Germany,
second - yes there is an solution for your problem, but you need an own server for that. (with Linux)
the Software for the Server is called “FSD-Server” (the old Vatsim used that), but you must compile that on yout server, If you have questions you can ask me.
for the FSD-Server google: “FSD Server Github”. the right site is from “kuroneko”.
