Transposing multiple related columns

While transposing single columns is pretty straight forward I need to transpose a large amount of data with 3 sets of , 10+ related columns needed to be transposed.

create table test
(month int,year int,po1 int,po2 int,ro1 int,ro2 int,mo1 int,mo2 int, mo3 int);

insert into test 
values
(5,2013,100,20,10,1,3,4,5),(4,2014,200,30,20,2,4,5,6),(6,2015,200,80,30,3,5,6,7) ;

select * FROM test;

gives

Transposing using UNPIVOT

select
  month, year, 
  PO, RO, MO
from ( SELECT * from test) src

unpivot
    ( PO for Description in (po1, po2))unpiv1
unpivot
    (RO for Description1 in (ro1, ro2)) unpiv2
unpivot
    (MO for Description2 in (mo1, mo2, mo3)) unpiv3

order by year

Gives me this

I will like to turn it to something like this. Is that possible?

Maybe use a query like below which creates rows as per your design using CROSS APPLY

select month,year,po,ro,mo from 
test cross apply 
(values (po1,ro1,mo1), (po2,ro2,mo2),(0,0,mo3))v(po,ro,mo)
