Stock Adjustment "New Quantity" Default Value

When you create a stock adjustment, the default value for the "new quantity" is 0. So by default, all of the stock is taken out if you hit save.

We use stock adjustments all the time for small adjustments, but sometimes our team forgets to update the New Quantity, wiping out all of our stock.

Instead, the system should default the New Quantity to the current inventory value, so that the variance is by default is 0.

This would reduce errors caused by user mistakes.
