IMHO it works as follows:
1. you define / selct the mapping template , e.g. "Microsoft Excel Defects".
The template defines whether you word with items based on a query, or Content based on document ID, summary and Project.
2. your template is set to items based on query and you select a query, e.g "quick query".
In your query definition you can define the project to work in and you can add the project field to the default columns.
The Excel Integration can only utilize the mapping and the querie you previviously defined.
