Custom Launch Parameters

[TacSmart 0]

I would like to find out if I can run a custom launch parameter to execute a script on the server when it starts up. It would have to be a command that would execute after the mods are all unloaded. I have tried using the mod Auto Commands For Rust but it does not work for me. 

 

The command I want to run automatically: spawns.config <spawns config file name>

 

As you can see, this is a command that relies on a response/ activation from the mod itself. I can see how this may not work with the custom launch parameter field on the control panel... but is this possible somehow?

 

Any help would be appreciated! I need this command to be ran every time the server restarts, as it controls the spawn points for players.
