DXT Settings : Anyway to get DXT looking less compressed for normal maps and light maps

When compressing Textures, the DXT is on / off. PVR has a 2bbp / 4 bbp option.

Anyway to get DXT looking less compressed for normal maps and light maps?

I am guessing it’s a fairly compressed DDS because the normal maps and light maps look bad, so I am trying to avoid compressing them with DXT, leaving as Jpgs in our project.

Is there any plan to open this up so you can add more quality or have a Normal Maps DXT option?
