Auto Fill The last Record Detail Selected From Drop Down

My table has 2 fields. One is a drop down of names from a lookup table, and the other allows input of text. After I press save the record is added, but to enter another record for the same named person i have to go through the selection process from the dropdown list again. How can I add another record consecutively to the same person without having to reselect them from the dropdown list after each consecutive save.
