Is possible to... (I don't know how to explain on title)

Is possible to make for example, a button that when clicked the skybox change for all servers and the new skybox stay to forever (on new and old servers) ? (only a example)

If yes, say only the thing I need to use (datastore, or something like that) , you don’t need to explain all.

Hypothetically, yes, however you’d have to use MessagingService and store the value of the skybox within a datastore, or use HTTPService and an external server.
