Pulling dynamic subitem information into a Monday Doc

We have a use case where we pull item and subitem information currently through an app to generate a pdf that we send to our finance team to generate sales orders and invoices. Currently the app isn’t the best to use and I would love to be able to replace it with a Monday Doc that is self generated from a template. The issue is that currently there is no way to pull dynamic values from subitems into a Monday Doc. Is there a plan to put this on the roadmap? Or is there a workaround that I can use without using an outside app to generate the document?
