That's what you've been missing for so long, but you were so hoping to get. The first plugin based on Shop-Script, which allows you to combine many products into one single product.
All you need is to select those products that need to be combined and to do so with a single button. As a result, you get the single product that contains information from different products. More detailed description of the functionality can be found in the documentation. I advise you to check it!
IMPORTANT! The plugin is still new...so be careful! It is recommended to make a backup before use.
