vRA 7 - Can't "Add Components" to an existing multi-machine blueprint

Hi everyone,

I have a blueprint that allows 2-6 Windows servers. but when I provision a Deployment with 2 Windows servers, I can't add anymore!

In vRA 6, there was the "Add Components" button when you click on the Multi-machine service, but in vRA7 I don't see that button anywhere.

Also, when I look in Administration > Actions, I don't see the "Add components" action listed, but I do see it in my vRA6 installation.

Any ideas? Am I doing something wrong?

Thanks!
