Is there any possibility of adding a new column (called estimate) in the excel that you provide to import invoices? and thus be able to link the invoice with an estimate already loaded in the customer's account. This would make it much easier to load invoices since nowadays we load them one by one in the system. We really need to speed up the invoice upload process but as long as it can be linked to the project estimate, so that we can see what is left to be invoiced. Thank you
