Drop Down Form Field Options Importing a list of Names for Fields

I am making a form for purchase orders. I am wanting to build a drop down table in a form that shows several department Names and their Budget Code. Is it possible to import or past a list of names or numbers at one time? Paste more than one at a time. How about Columns? Budget Code; Department Name; Section. Since each Budget code has a different department name and section name is it possible to select the three at once?
