Material sorting in F4

I have 3 materials and descriptions as 444100-- -SIlver,444300 -Aluminium ,444500 ---Bronze..

444300----- aluminium

444500-----bronze

444100---Silver.

Is there any possiblity to get the lsit of materials as

444100-----SIlver

444300-----Aluminium

444500-----Bronze..

i.e I want th system to sort the material based on the material codes not based on the material descriptions..
