3DSMax Object Colors to Object ID Mask colors

In my 3ds Max workflow, I assign the same wire colors to similar objects for easier selection in Photoshop or After Effects. Currently in Vantage, every object gets its own unique color, which breaks my workflow. What I'm looking for is basically what the VRayWireColor filter does in V-Ray - letting me maintain those color assignments from 3ds Max to the rendered output.
