Using the cRIO to control custom lights

Hello! I am working on a non-competition robot which uses this year's cRIO as the control system. I would like to find a way to control the brightness of lightbulbs directly from the cRIO. This means I need to find a way to make the cRIO control the current through one of its outputs (or an ouptut on the ditigal sidecar).

Is this possible?
From what I've been trying to figure out, its not. It seems that every output is either ground, a constant (uncontrollable) 5V, or the signal which sends information by changing the voltage from ground to some constant for a specified length of time.

In the past I have used a victor motor controller to control lights, but it would save the team $75 (for a Jaguar) and give me more options if I could figure out how to do it using only the cRIO.
