Can we move default file to another filegroup. sample code is given below

Sample code

ON PRIMARY
(
NAME = 'PRIMARY_01',
FILENAME = 'C:\METADATA\PRIM01.MDF',
SIZE = 5 MB ,
MAXSIZE =50 MB,
FILEGROWTH = 2 MB),
(
NAME = 'SECONDARY_02',
FILENAME = 'C:\METADATA\SEC02.NDF'
),

FILEGROUP EMPLOYEE_dETAILS
(
NAME = 'EMPDETILS_01',
FILENAME = 'C:\METADATA\EMPDET01.NDF',
SIZE = 5 MB ,
MAXSIZE =50 MB,
FILEGROWTH = 2 MB),
(
NAME = 'EMPDETILS_02',
FILENAME = 'C:\METADATA\EMPDET02.NDF',
SIZE = 5 MB ,
MAXSIZE =50 MB,
