Acrobat 9 pro designer -- how to populate drop down list




I down loaded the acrobat 9 professional trial version and have been trying to see how I can create a drop down list where I can input 500 names. I created the drop down list but the problem is the following. To enter the names in the drop down list I have to type each one and hit enter then enter in the next. I have about 500 names to enter and doing one at at time is not efficient. I tried to copy all the names and paste it into the drop down list but it will only paste the first name.

Does anyone know how I can enter 500 names all at once into a drop down list box?

I need a simple solution that can be made without some complicated code.
