Possibilty to strap down vehicles/objects on a trailer

I think this would be very possible to add modifying the nodegrabber

So i dont get rear ended all the time by the car im pulling when hitting the brakes

 

The thing I do, is just attach two nodes together in different places from front to back. It helps, but I think there's an issue with putting a car in park, and it still rolls. At least it's an issue for me.

 

Can you make several straps with the nodegrabber? (Not at home atm)
