Analytic function for grouping?

Question

Hello @all
10gR2
Is it possible to use an analytic function for grouping following (example-)query:
SELECT job, ename, sal,
  ROW_NUMBER() OVER(PARTITION BY job ORDER BY empno) AS no,
  RANK() OVER(PARTITION BY job ORDER BY NULL) AS JobNo
  FROM emp;The output is following:
JOB     ENAME     SAL     NO     JOBNO
ANALYST     SCOTT     3000     1     1
ANALYST     FORD     3000     2     1
CLERK     SMITH     818     1     1
CLERK     ADAMS     1100     2     1
CLERK     JAMES     950     3     1
CLERK     MILLER     1300     4     1
MANAGER     Müller     1000     1     1
MANAGER     JONES     2975     2     1
....The JobNo should increase group by job and ename; my desired output should be looking like...:
JOB     ENAME     SAL     NO     JOBNO
ANALYST     SCOTT     3000     1     1
ANALYST     FORD     3000     2     1
CLERK     SMITH     818     1     2
CLERK     ADAMS     1100     2     2
CLERK     JAMES     950     3     2
CLERK     MILLER     1300     4     2
MANAGER     Müller     1000     1     3
MANAGER     JONES     2975     2     3
MANAGER     BLAKE     2850     3     3
MANAGER     CLARK     2450     4     3
PRESIDENT     KING     5000     1     4
SALESMAN     ALLEN     1600     1     5
SALESMAN     WARD     1250     2     5
SALESMAN     MARTIN     1250     3     5
SALESMAN     TURNER     1500     4     5How can I achieve this?
