Use Azure ARM Template to create Service Bus Topic Subscription with Sql Filter?

I've been able to figure out how to setup an Azure ARM Template that creates/manages an Azure Service Bus Namespace, Topic and Subscription to receive all messages. However, the Microsoft documentation is extremely lacking still on ARM Tempates, and I am unable to figure out how to define a SqlFilter for the Subscription within the template that you can manage using the .NET SDK.

Does anyone know how to add a Sql Filter to a Service Bus Topic Subscription within an ARM Template?

Here's a link to the ARM Template I have for creating the Service Bus Topic and Subscription without Sql filter:

https://github.com/crpietschmann/azure-quickstart-templates/blob/101-servicebus-topic-subscription/101-servicebus-topic-subscription/azuredeploy.json

Also, here's the source of the ARM Template I'm referring to:
