add additional shipping options to free ground shipping?

Is there a way to add additional shipping option upgrades to the free ground shipping method.

Currently when a user receives free ground shipping on an item there is no available option to upgrade their shipping methods. If the user would like to upgrade from free ground to say overnight, or 2nd day air shipping for an additional fee their in no option to do so.

I believe lowmips.com has a UPSv2 module that will provide the functionality you are talking about.  I use this and am very happy with it.
