We use one store for multiple teamraiser events and right now it is a total pain to report on who has bought what. You can build a report that at least tells you who has purchased an item for what teamraiser event, but it will not give you the product details. You have to run a separate ecommerce report in order to see the product detials, and that report doesn't let you know what event it's for. So, you end up having to awkwardly merge two reports and it's a total pain and inefficient!
