Minimum stock quantity

[femo]

We need to use different signals/expressions to show if a product is in stock, out of stock OR with low quantity.

The problem is that we need it with different minimum quantities per product (i.e. "Product A" can have a minimum quantity of 5 and "Product B" a minimum quantity of 10). Below this threshold it would show a yellow sign and the expression "Limited quantity"

Is it possible? 

How?
