Another popup menu question

Is it possible to add to a popup menu by linking the cell with the popup menu to a column. as rows are added to the column, can they be automatically put in the menu of the popup cell?

If not, is it possible to get a long list from a colum into a popup menu without manually typing each entry or item in that popup menu?

What I'm trying to do is for Form entry. When a new customer is added, I can go to the table with the customer list and add another row with the new name, and then (hopefully) have that name automatically added to the popup menu list on the form table and form entry sheet.

thanks
