This will allow users to see clearly at the point where assets are close to being sold out....i.e. a orange icon. this will help drive urgency in the sales process whilst also helping the sales reps see the availability without needing to dive into the item itself or go to a report which takes the user away from what they are doing.
We're re-visioning the availability functionality and this was definitely something we wanted to accommodate (i.e. if all proposed deals exceed the availability, highlight it could be oversold!)
