I don't agree with you about having a software that "fixes" those clips from happening.
The clips typically appear because of dynamics, build of up frequencies at that point, and volume due to the lack of compensation of the previous two points.
I also don't agree with side chaining, because that doesn't do any thing to actually control any of the three points above.
If you're using groups and you do get the things sitting right, i would consider adjusting your group volume, because you get to maintain the ratios of your individual tracks but instead lowering the overall volume of that entire group. IE drums, bass (not sub i leave that to go into my master/premaster), leads, sound effects and fills.
If you're still having trouble, apply some group compression. I haven't experience RMS compression, because that particular component in reason's mixer isn't as versatile as i'd like. so i end up using a peak compressor.
But use the compressor as a compressor, i wouldn't recommend messing with the outbound volume, or input volume.
If that's not working, reconsider WHAT you're eqing and adjust group or individual volumes in the group channels (if you have them).
That's generally my work flow when it comes to identifying peaks, but i tend to get them early on and nip it in the bud.
I also tend to start lower in volume and then move up, rather than start at higher level. There's less room to go up, and you have less reference points to consider as well.
ps, i don't side chain any thing. I love how the layers work together to get things nice and fat. #teamwork
