Warthunder-Modification Available?

Dear Master, I am curious since I saw the world of warships there are plenty of modifications that can be applied on to the models, But in warthunder the modifications are not able to show differences on models, there are only one base model for each type. I notice this because the Leopard2PSO, with its speciale PSO dozer attached in front of hull, hope can see then here too! 

Unfortunately, I don't quite understand War Thunder yet. That's why modifications don't work yet. I have plans to try to do this. But I'm not sure if I'll succeed.

Looking forward!
