Dropdown list values from database

I need to use several dropdown lists on my registration form, all containing the same set of values (and it is rather a large set). The reason for this is I want to store details about the children of the person registering. Is there some way I can have the values for the dropdown list selected from the database or some other source, so that I don't have to set them up manually for each field? The problem with manual setup is that if I want to change the list, I have to change it several times.
Thanks.

Did you figure it out? I need to do the same thing-- pull a list of values from a non cb table into a dropdown menu for selection during registration and on the profile page.

No I couldn't find any way of doing it. I have just hard coded the values in.
