Create simple NAT list using AS3

Does anyone have an example of how to create a simple NAT list using AS3? I'm talking about the kind of NAT you would create in the GUI under Address Translation -> NAT List

We are looking to push a whole partition and the NATs are part of the partition so it makes sense to include them in the AS3 definition

From the documentation it looks as if I can create a NAT policy and specify source and destination address list objects, but this seems convoluted for what I am trying to achieve.

If this is, in fact, the way to do it, would someone be able to give me an example declaration for a simple NAT such as:

Name: Test_NAT, NAT Address: 10.10.10.50, Origin Address: 192.168.1.50
