AzureML - How to add hidden layers in neural network

Another title of this question can be : AzureML – missing "custom definition script" in "Hidden layer specification"

In AzureML modules – Two class neural network or multiclass neural network, I want to add more layers. As per documentation, by default there is one hidden layer, and we have option to specify the nodes in that hidden layer.

As per blogs, we can add hidden layers by specifying Net# script in "custom definition script" in "Hidden layer specification". Though in AzureML there is only one option – Fully Connected Case.

Am I missing something, or this option is removed by Microsoft. And ultimately how to specify number of hidden layers?
