Resolve - Deliver r3d media with reverse speed

I have changed the speed of an r3d clip in the conform section to -100%. In the color section it plays backwards, as wanted. But when I render it out, it changes back to its normal play direction. Is there as way to influence this?

Thanks in advance for your help!

Hi, are you rendering in individual source clip or one single clip mode?

I am outputting individual clips for a roundtrip to FCP
