Please add other Blending Modes to Calculations

For an effect that I am building, I need to happen a lot of things in a single layer. That is where the Effect/Channel/Calculations comes in handy. But unfortunately, the Blending Modes this effect offers are not the same as those for Layers.

E.g.: Hard Mix is missing. And that's exactly the one I need for my project...

Would it be possible to extend the effect with all Blending Modes?
