Hi dodwan ,
Thanks for your question.
I assume you're talking about the sales widget. You can easily change the statuses used to calculate these values, but it would need some custom coding.
Just take a look at this filter:
atum/get_sold_last_days/orders_status
You'll feed it in /atum-stock-manager-for-woocommerce/classes/Components/AtumCalculatedProps.php
Hope this helps,
José Andrés
