[Plugin: Easy Digital Downloads] Purchase Minimum

Is it possible to set up a minimum purchase amount?

I’m toying with including some very small digital images in my store and charging less than a dollar for them. It would be nice to set a minimum purchase so that if people only purchase those small images and not more expensive ones that I won’t have nickel and dime purchases hitting PayPal.
