Export invoice data with Zoho project link

Export invoice data with Zoho project link

Hello,
I was building global service project KPIs and I was wondering if there was a way to get the project linked to each item in invoices as part of the invoice export. Right now I can map individual items to my projects using a text field in which our finances manually write down the opportunity # to which the invoice is associated and I find a way to match the value from that field to each project's name (considering they were properly filled). What would really make my life easier is to be able to get the associated project from each item line which is populated through the project/books integration available. That way I could easily compare project budget vs actual billing without  fear of mistakes due to poor manual data entry.

I would be more than happy to provide you with more context if it !
Best regards,
Ludovic
