Tracked vehicle

Hello,

I working on tracked vehicle with 4 tracks, which means 2 on each side.
I found this amazing project and customize it:

UE4_Tracked_Vehicles

It works pretty well with casual 2 tracks, like normal tank or so.

So I have a 2 questions, the first one, is it possible to add 2 more tracks in to vehicle blueprint from that project? I trying to make it work, but maybe I missed something.

And second, If it’s not possible, or overcomplicated, can I add precreated animation for rear tracks in vehicle blueprint, just as an animation, when you move forvard - animation working, when you reversing - animation plays back, something like this, without physics?

Thank you so much if you have any answers.
