Multiple HDRI domes

With the New Vray 5 we now have to option use lightmix and thus we occasionally render a Camera with multiple Hdri’s active and use Lightmix to either mix or choose the best suited one.

Only issue we are facing is that we cant seem to make use of mutliple HDRI’s with the dome module. Only one can be used it seems. Is this correct or is there a way to use the scene manager with multiple HDRIs.

As an example we have one camera with 2 Different HDRI’s with the same horizontal rotation. And one camera with 4 HDRI’s and 4 different rotations.

Thanks in advance.
