Product variants or product category view problem

-- HikaShop version -- : 6.3.0
-- Joomla version -- : 5.4.3
-- PHP version -- : 8.3.30
-- Browser(s) name and version -- : Firefox 148.0

I’m pretty new to HikaShop.

I import products (Moodle-Courses via Joomdle) and some of these products/courses are pretty much the same with the exception of the dates. I would like to have these courses displayed on one page with checkboxes or radio buttons next to the different dates and one add-to-cart button.

The normal way, I think, would be to have a product and than create variants of it. But these products already exist. And I need the original imported products because they are linked to the courses in Moodle.
My first question is: Is it somehow possible to turn a product into a variant of another product?

I tried another way, created a category for these courses/products and have them displayed on one page in a category view. Now I have the dates (in the product names) on one page, but each one has it’s own add-to-cart button.
My second question: Is it possible to turn these add-to-cart buttons into checkboxes with only one add-to-cart-button beneath it?

It would be nice if somebody had a solution for one of the two problems so I could have the look I’d like.

Then, you can change the "Product selection method" setting to "checkbox":
www.hikashop.com/support/documentation/5...html#display_product
On the product page of that main product, you'll no have one checkbox for each option product.
