Help editing unique field

Hi, in another topic in the German forum, you provided a sample XML adapter for Google Product Listings.
I am trying to edit the Title and Description fields which are unique fields.
Example output
<title>Example - Online Store</title>
<description>This is a sample feed containing the required and recommended attributes for a variety of different products</description>

I want to change the title data to My Store Name, as well as the description but I can't seem to find where I edit this. Thank you!

I did find my answer under the unique tab where I can edit the X values. Just didn't see it!
