Foreign Keys and Reports in Microsoft Access?

So here is the deal. I have 2 tables. One is Product, the other is ProClass. The Product table holds the numerical primary key of the ProClass table as a foreign key. The ProClass table has 2 fields. The primary key and a text field.

Now, I want to make a report that shows all the fields of the Product table, but when it gets to the ProClass foreign key, I want it to show the value of the text field that foreign key relates to in the ProClass table. Is there a way to do this in the expression builder? I know how to do this with a query, and I could just make a report out of the query, but I would like to do it the way I mentioned above.

Thanks in advance
