Yes, you can. Just be sure to stay within the current rating of your bus bars, and organize wiring in a safe manner.
Perhaps unrelated: The linked bar seems to be rated to 250A, I'm skeptical. I had 100A Blue Sea bars that were quite a bit more beefy than those. I have the Fastronix screw terminal bar in the shorty and I wouldn't want more than 60Aish going over that little guy.
If you are really pushing around 200A over something like that, check the temperature of the bar during heavy loads. If it is heating up at all its underrated for the job.
