As a part of my studies, I am interested in modifying some constant properties of a medium like water. For example, in `Buildings.Media.Water` that cannot be accessed by Dymola (I opened it in Visual Studio Code), I am going to change a constant e.g. density. Is there any way to do so? or should I do it through partial medium?

This question is also applied to some thermo-physical properties like thermal diffusivity that I could not find it in the constants of water.
I would be thankful for your advise.
