MasterRig Template output question

Really enjoying W12. I am experimenting with MasterRig on a mix, as the presets from Steinberg are really helpful for clarifying the sound I’d like from a mastering engineer.
Q : If I render a file and want to just back off the overall output, so the waveform is retained without excessive leveling (the raw track has headroom) I’m not sure how to do this. Obviously I could go through the 5 effects and reduce the inputs/outputs; but I want to retain the sound - just not have the peaks cut off so much. What’s a good way to go about this? Thanks.
