You almost have it.
If you were using a lab power supply, and you put it in constant current mode (current source) the necessary voltage adjustment is done by the power supply automatically. You don't have to do anything.
If you don't have a lab power supply, you can mimic one well enough for anodizing by using a variable voltage source. You do this by constantly watching the current, and you adjust the voltage so that the current stays the same. The variable voltage source can be as simple as an ordinary lamp dimmer with a battery charger plugged into it. You start with the voltage source set to the lowest voltage you can set. As the anodization increases, you will be adjusting the voltage upwards.
