Subform Combobox To Only List Specific Values

I have an Employee's Development Objective main form , which has a subform that contains a combobox that lists all 'Job Titles' and 'Job Objectives' within the company, say such as:

Code:
IT Manager, Create Spreadsheets
IT Manager, Manage Staff
SQL DBA, Create Databases
SQL DBA, Create Spreadsheets
Managing Director, Manage Finance
Managing Director, Manage Staff

How do I get the subform combo box to ONLY display the Job Titles and Job Objectives specific to the Employees known Job Title? The combobox Row Source is presently:

Code:
SELECT qryJobObjectiveDetails.jobObjID, qryJobObjectiveDetails.jobTitle, qryJobObjectiveDetails.objective
FROM qryJobObjectiveDetails
ORDER BY [jobTitle], [objective];

The main form has a jobID number specific to the Employees job title.
