Applying texture sizes LOD to skeletal meshes?

Hi guys. I imported a skeletal mesh to UE. But im not going to use any extra geometry lod (the skeletal mesh is about 25k polygons and i dont plan to have more than one or two models at the same time in the screen) but i would like to use, instead a different texture size.

Is this possible? i have 2k and 4k textures, and i would like to use the 4k as default, but the 2k when zooming away.

Thanks in advance.
