For example, I might have a headphone product and want to have a 'maximum volume' variable for it. I would then like to access this variable and have it displayed as another piece of information in the specifications tab on the product page.
To be clear, I plan on doing it this way rather then through product variations or writing it in the description, because I have many products that would need this type of variable.
Furthermore, I would like to also be able to upload via csv file, the values for this variable (in bulk), due to the large amount of products that would use it.
I hope I have made myself clear enough for you guys to understand! Any help at all would be greatly appreciated.
