It's hard to find out what engine sound we will get, for example if i download a mod with a custom sound, and there's a soundpack that over-writes it, but is a low quality sound for that engine, i'd rather it doesn't over-write. Basically, it would be nice to have an engine sound menu, where there is each car laid out and what sound file it is using, allowing you to change the sound source for that engine. So you cherrypick sounds from each sound pack
