Compress CubemapArrays with BC6H?

Dear all,

I want to create a cubemapArray from script with copying different cubemaps into that Array and store it as an asset. The asset should be in BC6H-format.
To set the different layers of this Array, one can use the setPixels and getPixels-functions, but they do not support the BC6H format.
Also, you can compress 2D-Textures to BC6H using the EditorUtility.CompressTexture-function, but this only works for 2D-textures.
My workaround here was to extract the faces from a cubemap into a 2D-texture, then compressing that faces to BC6H and writing it back to the cubemap with the copyTexture-funcion.
But now I want to get these compressed cubemaps into the cubemap-Array. Does anybody know how I could do this? I can do this without any problems for RGBAHalf or RGBFloat-textureformats, but the setPixel-methods don’t work with BC6H and I don’t know how to use the copyTexture-Function to copy cubemaps into a cubemap-array.

Thank you much in advance

Or similar question:

did the function Graphics.CopyTexture work for anybody, when you want to copy a cubemap to a cubemap-Array?
