Is there a way to “add a product” to your current product with one click?

I offer photography services and have created a product for each type of photo service. I can make a cheap video while I’m doing the photo service so I would like the user to be able to add it with just a checkbox while they’re on the photography product page.

At first, I created the video as a separate product and just added a link to it in my photography products with the text “add a video by clicking here”.

I’ve recently purchased the “Add-ons” extension for Woocommerce. I replaced the link with a checkbox that simply adds the price to the photography product. That works better.

But ideally, I would still like the video to be added to the order as a separate product, rather than just as one notated line added to the original product.

Is there a way to have an option like the “add-on” that is just a checkbox, but it adds another product to the cart/order instead of just adding a line (and cost) to the product?
