How to split a DS utrace file into multiple utrace files?

How to split a DS utrace file into multiple utrace files? Our DS runs for a long time, possibly for 10 hours, and if we record all the trace records for 10 hours in a single file, the file will become very large, and loading it in Unreal Insights will be extremely slow. Could anyone please advise on how to divide the utrace data into multiple files, such as generating a .utrace file every half an hour during runtime?
