Using one Registration Form for more than one entity in Cart

Hello,

I am using Entity Registration with Commerce Registration to build a site to signup for Courses and Events. In my case, it should be possible for someone to signup and purchase more than one course at a time. Though in order for that to happen you would add your two entities to the shopping cart, then you would be presented with 2 forms to fill out, same fields since they are both using the Course Registration Type, but still two forms since you have two entities in your cart. This doesn't seem like the biggest of problems until you have people purchases 5 classes at a time....

So, I am curious as to if the entities are referencing the same Registration Type, is it at all possible to show only 1 form and have that form work for all entities, updating their slot inventory too? My idea is if you add 5 Courses and 5 Events to your cart, you are present with only 1 Course Type Registration form and 1 Event Type Registration form.
