Is it possible to create Auto Invoice Adjustments for orders over a certain $ amount?

We have a business need, to give a group of our customers a flat percentage discount off an invoice, but only above $2,500. Ideally this would happen automatically, because it is unrealistic to manage these adjustments manually.

I've read about Automatic Invoice Adjustments, and i figured out how they work, but i don't see an option to set a qualifying $ threshold. Does anyone have a suggestion?

Please advise.

Thanks,

Kailey
