Looking for some advice on cross model reporting for hosted Odoo.sh instance. Assuming we do not have access to change code. Is there any way can create a cross model report?

Honestly I cannot believe there isn't a built-in way to do this. It has to exist...

How can I generate a report that shows something like this:

order#, product_internal_reference, product_line, product_QTY,order_line_total 

"product_line" has it's own model with a list of available items,  and is set through a M2O field in the product model as a drop down. 

product_line on the product model IS set to Stored.

Thanks!
