If you happen to have a large number of jobs and want to change them all according to this topic; the script below should get the job done without having to manually click through each job/jobstep.
declare @Jobs table (jobId uniqueidentifier)
declare @Steps table (stepId int)
declare @jobId uniqueidentifier,
@stepId int
insert into @Jobs select job_id from msdb.dbo.sysjobs
while exists(select 1 from @Jobs)
begin
select top 1 @jobId = jobId from @Jobs
delete from @Steps
insert into @Steps select step_id from msdb.dbo.sysjobsteps where job_id = @jobId
while exists(select 1 from @Steps)
begin
select top 1 @stepID = stepId from @Steps
exec msdb.dbo.sp_update_jobstep @job_id=@jobId, @step_id=@stepId, @flags=8
delete from @Steps where stepId = @stepId
end
delete from @Jobs where jobId=@jobId
end
