Multiple Eye Textures

[sirtrippsalot]

I'm working with a custom eye model in Fallout NV. It requires multiple texture files instead of the single one that GECK supports. I can set multiple textures in Nifskope, but it will use the same secondary textures for all the primary textures, which causes issues as the textures are not all based on identical layouts. Is there any way to either set the nif to base the extra textures on the primary texture's name, OR, to make GECK allow for more than one eye texture?
