Hi,
No this is not possible by default, but you can potentially set a stock to unlimited (-1) on that product and use a custom product field to get the quantity information and display a message based on the value of that field.
To display the message it will require view edition, but the view depends on where you want to display the message.
If you want to display it on the product detail page, then the view to edit is "product / show_default", and use the same code than in this topic:
