Stock Added – Stock Remaining

I am wondering why this simple thing is missing from WooCommerce.

I am adding a stock of a particular product and I can only see what is left, how can I know how much I added after a week or month, sometime we restrock as well, so I think we need to have two columns showing that Stock Added Stock Left.

Also restocking should have a option to add stock again and enter so it adds to the stock field instead of directly editing the initial one, hope it make sense.

This way i added 10 stock, later i added another 10 so it becomes 20 and i will also know that i sold 12 or 15 based on stock left.
