Placing Legal Holds Manually

Has anyone ever placed legal holds manaully on holdsaveset?

Say you set legal holds for DA database:

select * from tblLegalHoldSummaries where CaseID = 1

update tblIntDiscoveredItems set LegalStatus = 426 where CaseId = 1 and LegalStatus = 420

EXEC [usp_LegalItem_UpdateSummary] @CaseID = 1

Then execute the stored procedure uspi_SavesetHold. Has anyone created code and variables to have uspi_SavesetHold place the legal holds?
