Updating lookup lists
From EHS Help
On the main screen open the Tools menu and select Settings.
Then click Manage Lookups on the left hand side.
In the Manage Local Lookup Lists screen, click on the lookup list you want to edit - in this case Host Referral Site.
The "New Entry" button is at the bottom for adding new items - or click on each item to edit, pressing Update when you're done with each item.
