I found some simple solutions:
- Assign material from the 3D modelling software and make specific name for example: MAT_WoodenFence
- Export to fbx
- Create new material or material instance in UE with the same name with the exported meshes material name in the same folder as the imported meshes
- Import the meshes in UE. In the import setting popup material tab, Choose to not import material and set the search location to local
The imported meshes will automatically searching material with the same name and assign. Works for multi materials too. Tested in UE5
