Add new column – Total Items

Hi Ankit, You did a great job developing this plugin. I must appreciate.

I want to add a new column to the exported file. The column should have information about total items purchased. Please advise how can add this new column.
e.g. Customer “A” has purchased
3 quantity of product X
2 quantity of products Y

So the report should display a new column
Total Items – 5

I understand we cannot have individual product names. I just want the total items purchased. Need not to display product details.
