Dispenser Cart

So I was having a normal conversation with a random guy on youtube.We talked about how it would be cool to have dispenser carts so that we can basically move dispensers.Well....I can't give you one in survival,but map makers might be interested in this...

It's basically a command cart with a dispenser for a face.
