Making this change will definitely require customization of the default theme as it is not an option you can set from within the JobRoller admin dashboard. So, technically it is possible, but not easy to gauge how significant this would be to someone to do as it is ultimately relative to your level of coding knowledge. AppThemes does not offer customization services, however we do have a
certified partners page where you can find developers for hire. If you make contact directly with an outline of your requirements, they can provide a quote for the work. Thanks.
