DirectX 11 Loading multiple textures into Texture2DArray

Question

Is there a way of taking an array of ID3D11Texture2D* objects and putting them together in a single ID3D11Texture2D* (with an appropriate ArraySize value) that will allow me to use a Texture2DArray in HLSL with them?

At the very least, how do you pass in the individual textures when creating a new ID3D11Texture2D object after you have set ArraySize to greater than 1? Do you need to pass in an array of SUBRESOURCE_DATA structs with each pointing to a texture to the CreateTexture2D function? I've been looking around for an answer to this, but the documentation seems severely lacking.

Thanks for any help you can provide.
