API for adding and configuring nodes?

When you download and install Orion SDK, the example how to add Node via PowerShell is here:

c:\Program Files (x86)\SolarWinds\Orion SDK\Samples\PowerShell\CRUD.AddNode.ps1

The sample is also available here: OrionSDK/CRUD.AddNode.ps1 at master · solarwinds/OrionSDK · GitHub

Will this also allow me to configure custom properties, select which items I want to monitor on the node and assign application templates?

Custom properties - yes

Select which items to monitor - limited flexibility here. This shows how to selectively add interfaces OrionSDK/NPM.DiscoverAndAddInterfacesOnNode.ps1 at master · solarwinds/OrionSDK · GitHub, but there's no granular control for other areas.

Assign application templates - yes. See OrionSDK/SAM.Application.ps1 at master · solarwinds/OrionSDK · GitHub for examples. Note that there is currently no API for customizing application templates, just assigning existing ones to nodes.

Thanks!  Being able to assign the App Templates is the only bit I really care about.
