Razer Naga: possible to change DPI on the fly through button binds?

[DreadBelch]

So my old Logitech G8 mouse had the ability to change DPI on the fly. Does anyone know if it's possible to do the same with a Razer Naga? Maybe you could bind an increase in DPI to one button and a DPI decrease to another button somehow? The Naga's Synapse software allows DPI changes and macros, so I thought someone may have come up with something. Thanks.

edit: apparently you can assign different sensitivity changes to buttons. i just can't figure out how yet.

edit 2: looks like you can choose "sensitivity" from a drop down list when you go to assign buttons to different actions or keys.
