Bake textures to low res LOD mesh in UE, possible?

I have a high poly mesh. I use auto generated LOD for levels 1-2 and I want to use a simple cube for lod3 (similar how planes are used for trees). Now, LOD 3 has different UVs, so I need to bake the material from LOD0 to LOD3. Is it possible to do directly in UE?
I know how to bake a texture in xnormals, but the high poly mesh has many materials so it’s not possible for this case.
