What are the steps to reproduce your issue?
Import a batch of invoices and a batch of payments journal items and try to reconcile the account receivable going to Account/Accounting/Actions/Reconciliation
What is currently happening?
There is not problem while importing the accounting movements, but when trying to reconcile is necessary to do it customer by customer, is a high volume, so we are looking some way to automaticlly reconcile this journaul items
What are you expecting to happen?
We need some automated action that reconcile all journal item, based on date, so it takes the oldest payment and reconcile with the oldest invoice
