Best calibration choice for ProMix HP?

Which preset calibration is best for volumetric water content and pore water EC for the pulse pro substrate monitor? Provided options all vary widely and the only options are mineral soil by default and then coco options and none are peat based. I find it hard to believe that something like this does not have presets properly calibrated for such a widely used medium. Please advise.

Anyone have any advice for this?

Sorry, but i guess you have to talk to the Support Team as there is no configration for this kind of organic Medium so far i can see. Im looking too for another config because im using floraflex 1 gal pot with 60% water Holding content.
