Report Tasks in Processing started

We created replenishment tasks with picking of 10 LPNs per task.
I need to create a report that more accurately demonstrates the various tasks that will be in progress.
To do this, I identified that the only screen that shows picking steps that have already occurred in the same task is the Nbr of Moves within the Tasks screen (UI-HTML: {task}s).

However, I did not find how to access this category through Web Reports. How can I find this? In the case of the screenshot, the report would have a column informing that only 1 of 3 pickings was performed.
Thanks
