You can do that using Odoo Studio - or custom development, if you're not on an Enterprise subscription.

Thank you Christoph. I do have the enterprise subscription, but the studio icon is not available when I use the Customer Statement button to create the report (see snipped screenshot below). I have looked in the reports list too and I cannot find one that matches the name. I am looking at creating a custom report that will do what I need it to do, but this seems like a lot of work when the report is already there, I would just like to edit the layout. 

My bad, statements work differently. Odoo 18.4 - and therefore soon 19.0 would have you covered with a much nicer layout though... See https://demo.odoo.com
