Block timings

Hello,
I would like to create a simple way to see how long participants took to complete each block of questions.
Currently, I have timing questions set up for each page, but have export all of the data and spend ages playing with it in Excel to be able to get the summary I need. I have also tried to create reports, but there are a lots of page timings to add and edit to show the relevant data (I only care about the Page Submit timing).
Ideally, I'd like a report that has the min, max, mean timing for each question, organised by block, and then a final total row for that block. Even just the final block totals would be helpful for now! Like this, but with many more questions!:
The blocks are also within a table of content which has prevented me using a few other methods I've tried.
Is there any way to do this? Any advice would be greatly appreciated!
Best,
Ben
