I have a new App with datasource added.

I added a Blank View and hooked up a Combobox and its data settings.I can view it in the browser.

All good But, I need the combobox Data Text Field to be different than default.

In the data populating the combobox there is a job_desc field. Id like to modify the combobox Data Text Field to show 

jobNumber - job_desc

and keep the Data Value Field jobNumber.

Anyone know of a tutorial or how to add a template to the combobox?
