Question : Report based on query ... can I see other table fields ?

I'm new to reports in Access ... hope this is a simple question.  

When building a report, I have it based on a query (record source is a query).

Problem is now that report is nearly complete, I have 2 more fields I would like to add to the report that are not in my original query.  I was hoping to simply add the fields by clicking the "Show All Tables" button in the "Add Existing Fields" window, but the button is not there.  I assume the button does not show up becaue my report is based on a query because if I create a new blank report the button is there.

So question is, can I add fields to a report if the report is based on a query .. and if so, how would I do that ?

Thanks

Yes, open the query in design mode.  Add the two new fields.   Open the report and you can add the new fields using Add existing fields
