Tie-Wrap Poly Lines in the Same Trench?

My system has 12 zones with 4 zone valves per valve box. When running 3/4" poly pipe from the 3 valve boxes out to the sprinkler heads, the 4 lines exiting the boxes will be run in the same trench initially. Question: With 4 poly lines in each trench, would it be a good idea (or not) to loosely tie-wrap them together every 10 feet or so? Trench depth is about 12" max. in a freezing locale. What about further away where there are only 2 or 3 lines in a trench? Tie-wrap or not?

You could put a red bow on them while you're at it, but why? What do you think your idea will accomplish? If you have any consideration for the repairman, you will make certain that none of the lines lays atop another.
