Best way to add options to checkout with WooCommerce

Trying to get my head around this a bit. Not sure WooCommerce can do it natively.

I sell X product which is downloadable images, I want to offer Y product (physical prints) at checkout (which is determined by an option within the WooCommerce product and is relatable to Y) as an optional add-on.

Can anybody recommend the best way to do this? I could probably code this in, but wondered if there are any native WooCommerce features or an add-on that would do this?

To be clear, I’ve already realised upsells won’t work, because I want this to be on checkout and it has to be related to the product in the basket.

Any help appreciated.
