Shared selling

I would like to see the ability to sell objects with a partner, meaning if someone builds an object, and someone else scripts it, for example, when the object sells we would each get half the money.

Having done this with our pet dogs, it would be extremely helpful for accounting purposes. Right now, we need to keep track of how many sales we've made and manually split the proceeds. Would be so much easier if we each got half the sale money automatically.
