It sounds like you're looking for a way to automate the process of paying invoices in Odoo, so that you can pay multiple invoices with a single button click, and have the payments sent to the bank automatically on the invoice due date.

There are a few ways you can potentially automate this process in Odoo:

1. Use the Automated Payment Order module: This module allows you to automatically generate payment orders for invoices that are due. The payment orders can be sent to the bank automatically on the invoice due date, without the need to manually create and confirm them.

2. Use the Payment Acquirer module: This module allows you to configure different payment acquirers (such as banks) in Odoo, and allows you to automatically create and confirm payments through these acquirers.

3. Use the Bank Payment module: This module allows you to create payments directly from invoices, and it will automatically create the bank payment file.

4. Use the Account Payment module: This module allows you to register payments for invoices and automatically generate the bank files.

5. Automate the process by using the Odoo Studio or by creating a custom module. This would require some development knowledge and customization.

It's worth noting that these modules are not part of the core Odoo, so you will need to check if they are available for your version or you can download the module from Odoo App store.

It's also possible that the bank system you have linked to Odoo, Ponto, has some limitations in how payments can be sent, which is why the process is more cumbersome than you'd like. In this case, you may want to check with Ponto support to see if there are any additional options or settings that can be configured to streamline the process.
