Encode To Texture Array?

[Raildex]

Is there a possibility to encode a texture to a Texture(1D/2D/3D)Array?
There is a cubemap encoding only.

You should be able to use the raw encoding apis and then build a file from the output yourself, but I don't have a ready solution for that

How would I build such a file?
