How can i create diskpart /s file to create a logical disk?

like here
select disk 0
clean
create partition primary size=200
format quick fs=ntfs label="system"
active
assign letter="s"
create partition primary size=5000
format quick fs=ntfs label="windows"
assign letter="c"

My question is:

How can i continue to create the extended logical partitions?
