Unable to attach a new Network Interface in a "newly created" Virtual Network to a Windows VM

I have a VM that has a virtual network and an interface attached. I am aware you cannot detach an interface without attaching a new interface to the VM.

However, when I try to attach a new interface, it makes me create a new one (doesn't use the one I have already created with a new virtual network & interface). I can deal with it but when I create a new interface, the Virtual Network option is grayed out (see attached screenshot Azure.JPG) and doesn't allow me to pick a existing virtual network or even create a new virtual network. Is this by design?

What are my other options? May be keeping the disk and creating a new interface? If this is what it takes, then I would like to leave the existing users as id and their profiles and data in the existing VM. Please help.
