Which hooks can add data to existing reports in woocommerce-admin?

I am trying to modify the sales reports in woocommerce-admin analytics. Currently the standard reports compare current sales with last year’s sales. I would like to add sales targets, so that current sales can be compared to sales targets.

I have seen the add-report example:

But instead of adding a new report, I’d like to add a simple "sales targets" dataset to the existing reports.

Which hooks or filters should I use?
