You can set up default entries in the Address Book; Opportunities; and Customer Service pages. When you create new entries; fields specified in the default entry are already filled in for you. For example; if you know all your Address Book entries will have the same city and state; you can specify these fields in the default Address Book entry.
Default entries are user-specific; so each user in the Address Book can have a different set of default entries.
Select Edit > Default Entry.
Select the fields you want to set as default values and enter the values in those fields.
Click Add Field(s) to browse and select more fields. To remove a field; simply click the X mark.
Click OK to save the changes.
You can now edit the Default Entry for many users at a time by going to Administration > Settings > [Module of Your Choice] > Default Entries
