Has QBO implemented the ability to associate multiple transactions by customer with a single project? I'm using projects and occasionally need to issue an invoice to a customer within the project (a project sponsor, for example). Since I have to select the Project as the Customer, I've been putting the actual customer name in the Bill To field. This works for tracking within the project but I won't see the transaction under the Customer activity. 

Is there any way to have Project-related transactions appear in a Customer's activity? I don't want to make the customer a sub-customer for project purposes, because the same customer might very well decide to sponsor other Projects in future.
