Product Groups with same stock messages

Hey there,

is it possible with your plugin build Stock message groups?
For example Group A:

• In stock text: “In stock”
• (can be backordered) text: “Delivery time: 10 business days”/li>
• Out of stock text: “out of stock”

Group B:

• In stock text: “Only %s left in stock”
• (can be backordered) text: “Delivery time: 20 business days”
• Out of stock text: “Will be back soon”

and so on.
I think it wouldn′t be handy to just have the global option and a custom Product option. Because if i would have 2 different groups i would have to customize a lot of messages for products which shouldn′t have the default message
