Excel 2011 :: Pivot Table Filtering On Values In Specific Subcolumn

Is there is some way to filter based on the value in a specific subcolumn.

Using the example of a list of salespeople and their transactions over the year, who sell multiple products, the PT is Sales Person name for the Row Labels, and Type of Product for the columns. The resulting PT has 3 columns, for each of the products - e.g. table, chair couch, and the Values are the total number of that item sold. Is there any way I can filter, so that I will see only those sales people who have sold 3 tables or more lets say. (Thus enabling me to quickly see what other products those sales people have sold.)

(The actual situation is a lot more data heavy than that - it is actually a list of donations for a non-profit, coming in from hundreds of people, across a dozen different categories; I am trying to analyse the extent to which people who gave for a particular category (Direct Mail solicitation) also gave across other categories.

So far I've manipulated things by inserting a '% of row total' value into the PT and then using countif/sumif functions outside of the PT to figure out how many people donated solely to this category (= 100% of row total), and how many donated to other categories too (= more than 0% of row total, less than 100%), which gives me a decent summary of sole donations to this cause vs other categories too, but doesn't visualise what the actual other categories donated to were. I've also investigated making a PT of the existing PT, but I'm not sure if that's even possible...)

(I'm using Excel 2011 for Mac, but if there's some other version that would make this possible, I may be able to use another computer.)
