Hi! I don't believe that there's an automated way to do this in Braze. Klaviyo's a bit different in that regard, as it allows you to look at products within the platform, whereas Braze puts more focus on integrating with analytics platforms where you could do this and more.
If you really want to have this data visible in Braze, I'd suggest setting up a webhook that's posting product information (from the purchase event) to each user profile in the form of an array or nested custom attributes. You'd still have to export in order to look at the products for all users. (Disclaimer: this will count towards your data points usage)
The proper way to do this would be to take advantage of the currents integrations and send the data elsewhere. Amplitude is great for product analytics (product as in your app or website) and it gives you multiple different views with as many dimensions as you want; plus a great attribution system.
Looker is also great for this type of analysis as it can surface your entire database and marry Braze campaign data to the rest of your ad platforms and all user/order data. If you install the out-of-the-box Braze Looker Blocks, you don't need to worry about building dashboards and reports manually.
