You know you can just have multiple page design blocks for multiple pages right?
I use it for construction budgets and contracts so the number of line items always changes per project but I layout my page designer like this:
Block 1 - Invoice header with project name, customer details and my company details
add “look up” column element that is linked to my budgets to pull in all of the line items (usually never fits all on one sheet so I see where it got cut off at and continue that on the next block)
Block 2 - “look up” column for budgets continued
Block 3 - Invoice footer with terms and conditions.
Yes this is still a multi-step solution but it is all contained in airtable so there is no need to be exporting and importing into different workflows!
