Problem assignment of material parameters (properties) in porous materials

I am using poroelasticity module. There are porous material and fluid in the model. When I assign the properties of porous material or fluid, I need to choose which domain I should assign. The fluid and porous materials are at the same domain, because fluid exists in the void of porous materials. So after I assign the properties of the porous materials, for example, density, to a certain domain, I need to assign the properties of fluid to the same domain. But the question is that after I assign the properties of fluid to this domain, the assignment of properties of porous materials will be overridden by the properties of fluid.

So my question is that how do I assign the material parameters of fluid which exists in the void of porous materials to the domain? Thanks

Check Phase Change model from Heat transfer it will give you an idea how to assign properties to porous matrix
An alternative method (equation wise) is shown in Boiling of water model (check definitions part: kappa Cp etc.)
