you can either
1.create 10 seperate identical objects which are coded with a family (not too great a method, but it works, and you can easily pick on demand.)
2.use the pairer plugin to pair 10 instances which each object. (don't ask me how; I don't use it a lot, but that's what it's meant to do.)
3. spread a value and pair them according to the value. (not very flexible mind you)
