I guess there is a little confusion in terms of modes. My suggestion is to leave the existing display modes, which are "bulk, timestamp, incrementing and timestamp+incrementing" and add a new querier mode to have "query, table and storedprocedure". In our case bulk with storedprocedure should work fine
