Editor utility tools for assigning textures

So simply I have 3 textures for each material instance that I have to plug in the diffuse, normal, and rough/metal/ao parameters of a material instance.
I’m sure it should be a simple task but I search everywhere and all I can find is changing textures at runtime with help of material instance dynamic. Any idea how can it be done in the editor with blueutilities?( by selecting the material and 3 textures at the same time and execute the command)


Please help!
