How to check invoices

My problem is to import my invoices, I go to Accounting -> Invoice Client -> Import. From there, I placed my EBP Excel file containing all my invoices. I select different fields to import (customer, date, product, price, quantity, taxes ...), but I cannot see the payment field (this is the payment date, amount paid ...). Basically, I can import my invoices with customer name, invoice date, different payment lines, VAT ... but I can't import to indicate if an invoice was paid, what date, what? The amount has been paid ... I cannot find the corresponding fields while importing!

I didn't arrive, so I tried to import all my invoices without paying them and then import the payments separately in the menu "Accounting" → "Payment Client" → "Import". The problem is that I cannot link the payment to the invoice during import.

I hope that was clear. More generally, how do I import an already paid invoice? I have over 4500 invoices to import, so I really need something automatic. I also tried to go through the "bank statements" menu, I can solve several invoices at once, the problem is that I cannot enter the correct payment dates (at least in any case I cannot just specify the date for all invoices, with which I disagree)
