Manually adding sites to exclusions for Identity Safe Autofill

I understand how to add sites to the exclusions list (by ticking the box on a site when the Identity Safe login comes up), and I know how to remove sites from the exclusions list.  However, what I would like to do is manually add a site or URL to the exclusions list.  The are several sites I go to regularly that have forms such as an email signup, and Identity Safe is attempting to fill these in with my data (which isn't the right data for that site, either) - but it never gives me the opportunity to add the site to the exclusions list.  This is not on all sites - just some.

 

For example, I administer a php-based forum.  When I go into the user management section of phpBB to change a user's information, it autofills my information for the user.  I don't want this.

 

Is there something in the program, the registry, or somewhere else, where I can manually add that I don't want Norton to attempt to autofill?

 

Thanks!

There are two options to solve this:
1. Log off from Identiy Safe, and then it will not fill the forms.

2. Wait until it fills the form, then delete the data it put in, and write the one you want to write in.
