Is it possible to disable the auto submission of expense report in Touchless expense?

Summary:

We are planning to implement Touchless expense for our client. We want the employees to send the corporate card expense receipt to the touchless expense mail. We expect the touchless expense to match the receipt with the corporate card transaction and attach the receipt automatically to the expense. But our client does not want the expense reports to be auto submitted. They want the employees to select expenses and submit one consolidated expense report monthly. in some expenses the employees need to add additional comment and then submit. Is there a way to disable the auto submission of expense reports
