Auto connect PDF invoices to existing transactions

Hi! I'm new here and trying out Akaunting.

I'm wondering if it's possible to upload PDF invoices (expenses) and auto-connect them to existing transactions. This way we'd like to level-up our financial administration.

The 'Receipts' app seems to do something like this, but this only supports images (no PDF). Does anyone have an idea on how we can do this? Maybe an app suggestion?

By the way, it would also be great if this app supports the functionality of sending the PDF invoices from your mail to akaunting. Would happily be paying for this.

Anyone who can help me? :)
