Hello, you should be able to export the Time Tracking details for all sub-elements of the Board. Currently, it only allows you to download the time tracking for each element.
Hi @rrivera ! 
The native export currently only includes the main items, not their subitems. If you need a full export of time tracking data (including sub-elements), you might want to try our Time in Status for monday.com.
It provides detailed time reports across boards, items, and subitems, and you can easily export everything to CSV, Excel, or PDF for analysis or billing. It’s a great way to get a complete picture of tracked time in one place. 
Hello @rrivera ,
In terms of time tracking reporting, I’ve put together an article covering all the available native ways to report on time tracking in monday.com, including subitems. I hope you’ll find it helpful.
