You cant Select Polygons and Assign them a new ID inside UE4. Materials have to be set inside Blender! If you Export the Model it will take all those Material IDs assigned to all the different polygons in the right order and show you the Slots inside UE4.
Here is a Example how its done in Maya/Max you can surly find a Tutorial how to do it in Blender. Or tell your freind to do it. But be aware more Materials on a Mesh = More Draw Calls = Less performance!
