This is why there are so few default settings to set in Unity3D:

SPOILER: Because you can do it in code.

MeshPreProcessor.cs:

using UnityEngine;
using UnityEditor;
using System.Collections;
public class MeshPreProcessor : AssetPostprocessor {
void OnPreprocessModel () {
 ModelImporter modelImporter = (ModelImporter) assetImporter; 
 modelImporter.meshCompression = ModelImporterMeshCompression.High;
 modelImporter.globalScale = 1.0f;
 modelImporter.addCollider = true;
 modelImporter.generateAnimations = ModelImporterGenerateAnimations.None;
 }
}
