Discount function for several themes (wallpaper, AOD, icons, themes) at the same time

Background:
Currently if you want to activate a discount/coupon you have to add apps one by one. If you have a lot of apps this get repetitive and time-consuming.

Related Menu or Feature:
Copy discount function for content or a discount upload function.

Detail description of the Feature Request:
I would like a discount function for several themes (wallpaper, AOD, icons, themes) at the same time, so that, for example, a predefined Excel CSV table is uploaded and the discount is imported from this. At the moment it is a difficult detour to set up a discount for several themes for a certain period of time. It would be very helpful if you could enter a discount of, for example, 30% and then apply it to multiple themes. Without having to recreate this for each theme.

Benefit:
Faster, more effectively and save time
