Dx12 multinode API's

Hi, I apologize for creating multiple questions here for dx12 since information is sparse so far. Anyway in some Dx12 api's, there's a node mask for multiple node support, for e.g. D3D12_COMMAND_QUEUE_DESC for CreateCommandQueue & CreateCommandList itself has a node mask. However, these API's are all called on the D3D12Device itself, and when creating the D12Device (D3D12CreateDevice), there isn't an option for it to be a multi-adapter device; you just pass in a single adapter. So what is the point of the node masks in the other API calls? Is there some other use case I am not aware of yet? Thanks!
