label for Summarize row in proc report

[Batman]

How can I force the word "Total" for the summary line in the code below?

data a;
input x 1. y 1.;
datalines;
10
21
31
22
;
run;

proc format;
value grp
1='A'
2='B'
3='A'
;

proc report data=a;
col x n;
define x / group format=grp.;
define n / 'count';
compute before;
x = 'Total'; /*column or grand total*/
endcomp;
rbreak before / summarize;
run;
