Equations form results

I am a new user of PrePoMax software.
Until moment that I am finding that soft on the internet I was mostly used SolidWorks Simulation.
In SWS there was very good option to displaying map of “equations of results”.
Choosing this option mean that software displaying your custom map.
For example if i need the map of Dang Van fatigue criterion I can use that option and input my equation using primary stresses of whatever I want to.
Look for this option:

Is it possible to add this option to new bersion of Calculix?

This was discussed some time ago but has to wait for its turn: Postprocessing: load factor contour plot - #4 by Matej
