Hi there 
If I understand correctly, you’re selling a bundle made up of six items, with two of those items being customizable, and you’d like customers to see their personalization before placing an order.
This can be a bit tricky because most bundle apps focus on grouping products together, while most personalization apps focus on previewing a single product. Finding a solution that does both well isn’t always straightforward.
One approach worth exploring is using a product personalization app such as Easify Custom Product Options. It allows customers to enter custom text, upload images, and see those changes reflected through a live preview on the product page. This works particularly well when the bundle is sold as a single product experience and the personalized elements can be represented within that product.
For example, if two items in your bundle are customizable, you could collect the personalization details for both items on the same product page and display those customizations within the product preview. This gives customers confidence that their personalization has been captured correctly before they add the bundle to cart.
That said, if you’re looking for completely separate live-preview windows for each individual item inside the bundle, you may need a more advanced configurator or a custom-built solution, as that type of setup goes beyond what most standard bundle and personalization apps currently offer.
Since you’re still in the planning stage, I’d recommend mapping out exactly what customers need to customize and what they need to see in the preview. In many cases, merchants find that a single, well-designed personalization experience is enough to communicate the final result without requiring separate previews for every item in the bundle.
It would be helpful to know what the two customizable items are (text personalization, photo upload, logo placement, etc.), as that will make it easier to suggest the most practical setup.
