transpose in one step instead two

[SASPhile]

Can this be done in one transpose data step?
proc sql;
create table access_v1 as
select Sales_Group,Product,sum(Sales_CY_Mth) as sls_cy_mth, sum(_2010) as S_2010, sum(_2011) as s_2011
from acess.acess1
group by Sales_Group,Product,Customer_Segment;

quit;


PROC TRANSPOSE DATA=access_v1 OUT=access_v2(drop=_name_) suffix=_acess2010;
BY Sales_Group ;
ID Product ;
VAR S_2010;

run;



PROC TRANSPOSE DATA=access_v1 OUT=access_v3(drop=_name_) suffix=_acess2011;
BY Sales_Group ;
ID Product ;
VAR S_2011;

run;

Can you provide some sample data (in the form of a data step), as well as the final file you wish to achieve?
