How to: IVAO "Altitude" client customization

Hello,

Thank you for reading this.

Before posting this I did a research but couldn't find anything.

As is known, IVAO client named "Altitude" displays aircraft models taken from the "MTL" library. The VATSim client "vPilot" reads the models already installed in the flight simulator and displays those according to various sets of rules.

I am interested in making Altitude to read and display the models that are already installed in my sim exactly as vPilot does. If is possible for you to tell me what files to edit/make in Altitude in order for it to read and display the already installed aircraft models in my sim instead of displaying those from the MTL, this would be really helpful.

Thanks
