Under company settings, in the mailbox details section, you can turn on the feature that will process an E-mail attachment as a single item.
Essentially, AutoEntry will not assess the attached files in the email and will process the first page only of that file. Any additional pages in the file will not be extracted but will remain as part of the processed page for reference.
Example is for submitting an expenses style invoice where the claim is on the first page in the file and the subsequent pages are the multiple receipts that made up the claim. These receipts will not be processed by AutoEntry but will be kept with the claim page as reference to the claim.
