Removing Sensor Dust in R3D files?

[Dorian Weber]

Those were my first shots.... and of course in the blue sky, sensor dust shows up.
Easy to remove it in Post; After Effects or Photoshop or so, but the problem is, they want the original R3D files.
Is there any way I can remove those dust spots?
Any software which can output in R3D?

Would like to know a fix for this as well before i really need it.

The spot needs to be fixed near the end of the chain as you can't touch up the clip and spit out a native r3d file again.

that seldom happens.....usually the spot is from the start to end, unless you pan from a sky into a darker area
