HDL to update / create Cost Centre Managers (PER_GL_COST_CENTER_INFO)

A customer I support has approximately 1,500 Cost Centre Managers defined across 4 different Departments.

I can see that using this SQL:

-- cost centre count per department

	select hov.name dept
		 , count(*)
	 from hr_organization_v hov
	 join hr_organization_information_f hoif on hov.organization_id = hoif.organization_id
	 where 1 = 1
	  and hoif.org_information_context = 'PER_GL_COST_CENTER_INFO'
	  and hov.classification_code = 'DEPARTMENT'
	  and sysdate between hov.effective_start_date and hov.effective_end_date
	  and sysdate between hoif.effective_start_date and hoif.effective_end_date
	  and 1 = 1
 group by hov.name
 order by hov.name

When the customer first went live, most of the Cost Centre Manager setup was done using HDL against the "Organization" Business Object, and since Go Live a few hundred have been set up via the front-end in the "Manage Departments" screen.
