Order to Project Association

The new project object type can be associated to almost any other object type including default and custom objects. However, when it comes to Orders, Hubspot doesn’t allow to even create a new association type.

I assume the standard use case for onboarding projects is to associate it with the deal but in my client’s case it is more useful to associate it to the order since order might have a little bit more information about the delivery that would be useful for the project.

Is it possible to add an association between these two objects?
