Tricky question on Connect By Clause Urgent!!!!!

Question

Hi All,
Can anyone tell me is there any way to use connect by prior clause with group by statement?.Or is there any alternative to connect by clause.?
I have a stored function which is having select with connect by clause.
I use that function in the select query for my reports.But now I want connect by clause to run against group by query.
I have a stored function which I use for most of the reports.I want to change connect by clause on the view based on group by clause which gives me an error.And also I cannot use Insert statements in a stored function
which I use in select statements.Is there any alternate way to do this???
Thank u all...

For given parent_task_idI would add:
SELECT task_id, wbs_level, parent_task_id
FROM pa_tasks
WHERE task_id != :given_task_id
START WITH task_id = :given_task_id
CONNECT BY PRIOR task_id = parent_task_id;
