I understand that woocmmerce works this way, but that's why ATUM is here to improve the lives of users 🙂
We share what is a big problem for me (also for my friends who use ATUM) in order to improve the plugin.
I know about the export, I use it for bigger promotions. But it would be more convenient for me to make changes by STOCK MANAGER itself, because I see the photos of the products and it is more convenient for me.
I believe that this type of functionality can be added to ATUM and it would not be very difficult. I'm sure it would help a lot of people and bring extra income to your company. I personally would pay for such functionality.
If in doubt whether it would be useful to consumers. You can run a poll.
