Is it possible to add an attachment to a Craft Commerce order status email? I'm trying to figure out a way to attach an asset file to a Craft Commerce order status email when a user purchases a product- the user would be purchasing the file and I'd like to attach it to the order status email that's sent upon completion of purchase.

I see that the Contact Form plugin has a similar functionality:

Is it possible to do something similar in Craft Commerce?
According to How to attach an order PDF in an order confirmation email?, it is currently not natively possible as of Craft Commerce 1.1.
