approving filtered Emails from Outlook on my iPhone

I have setup security rules that filter incoming Email based on certain criteria and send them to me for approval. In Windows Outlook I have the option to Approve or Reject these Emails. On my iPhone the Outlook app does not have that option. There used to be a way to do it from the Web Mail but that has been removed. It is also this way on the Android version of Outlook. Has anyone know a way to approve these Emails without having to drag my laptop around with me?

Thanks

Matt
