Invoice design - preformatted invoice

Good day!
I was investigating the invoice designer tool and it seems very powerful.
I couldn’t find out if I am able to only print the content and not the labels for each item. This is because I already have preformatted A4 invoices and I just want to fill in the content in the corresponding positions.

It’s possible but not simple, you’d need to replace the field stacks (ie, $accountDetails, $accountAddress) with the individual field variables.
