Progressive Sampler with unfiltered Render Elements

[Jon3D]

For certain reasons I have to use the progressive sampler for some Renderings. I want to include the VrayWireColor render element but I need it unfiltered. Unfortunately I notice that its not possible at the moment to render the elements unfiltered with the progressive Sampler.
Did i have missed some Settings or is there a workaround? I know I could render it twice with different sampling methods but I try to avoid that yet.
kind regards
Jon

The unfiltered elements will not render quite correctly right now with the progressive sampler. I'm not sure how to implement this yet.

Best regards,
