Make Stock Management Per Product (like Sellix) Remove Shared Warehouse System

Currently, Billgang forces sellers to assign serials from a shared "digital warehouse" across products. This system is limiting and inefficient for sellers offering unique digital goods.

For example, I sell Instagram accounts with different stats (e.g., Aged 2008, Fresh 2024, 2.7K followers, etc.), and each product has different quality, quantity, and pricing. There's no logical reason to share the same stock source between these.

Request:
Please allow each product to have its own serial/stock list, just like Sellix does. This would:

• Make inventory management much easier

• Eliminate confusion between unrelated product types

• Match real seller workflows better

• Help automate restocks per item

Thank you for improving the platform for serious digital sellers.
