Plugging displacement into other nodes (gradient, add etc)

[michaelmorin]

Hello,
Is there any chance that we might be able to plug our displacement maps into other nodes soon?
Currently there doesn't seem to be a way to plug anything into the displacement node other than image textures or the C4D noise shaders.
I would like to be able to plug in Octane's own noise or marble generators or more importantly, I would really like to be able to use other manipulator nodes like the gradient node to control the contrast of the maps or math nodes to mix and combine displacement maps together but sadly, if I plug my texture or c4d noise generator into any other node before it hits the displacement node, it stops the displacement from rendering at all.
Any help appreciates

Thanks

I didn't find the right solution from the Internet.
