I was wondering if it's possible to add a custom field/characteristic which a user in the shop can define himself. It's the same idea as the engraving which apple offers for their products. Let's say a user wants something engraved on a product, or needs to add some information to the order of that specific product. As far as I know this is not possible with the current features of hikashop, but perhaps someone can give me a pointer as to how to code this in php. I'm not completely familiar with the structure of hikashop (i just started using it), so help would be amazing!
Thanks in advance!
