Administrators can easily customize which fields act as "Suspect Link" trigger fields. Here are the steps:

1. Login using an account that has 'Administrator' privileges.
2. Click Settings on the top-right, and select Customize Accompa from the menu.
3. In the "Customize Objects" section, click the Define "suspect link" trigger fields link.
4. On the resulting page select the object fields you'd like to mark as suspect link trigger fields.

Now whenever changes are made to these suspect link trigger fields, any downstream relationships will be flagged as "Suspect Links".
