Multiple sound xml for a vehicle

[Marc76]

Hi,

Is it possible to specify multiple sound xml references within the tractor xml?

I'd like to keep the standard sound xml for the motor configurations, but specify a new sound xml for a new motor configuration. For example I've added a turbo engine option and would like that to reference a different sound xml. I don't want it as a different tractor mod, as I'd like the option of upgrading via workshop to the new engine option.

Is that possible, and if so, what would be the necessary format of the motor configuration tags?

Thank you
