Leasing products to customers

We are a retailer who use the Distribution and Ecommerce modules.  We have implemented a leasing program where customers can lease the product vs. buying outright.  In this scenario, we ship the product to the customer and then “transfer” the inventory to a virtual warehouse so that we can account for it.  We started using the TR order type but this is very cumbersome.  Are there others who are leasing products to their customers and if so, how do you track it?  We have looked at LeaseQuery, but it is not the right solution because they are more for if we were leasing the product for our use.  TIA
