The idea of an additional column for information has been brought up a number of times by our users.
Unfortunately, adding additional columns or information in one part of the app transcends through the app and leads to quite an extensive development overall.
We have looked into this a few times and found that it could consume a huge amount of development availability within the app that can be devoted to our top requested features.
Can I suggest using an existing column that can be renamed? Or storing this information as part of the product description within your sales codes?
