Outlook Classic - M-files - Save Attachments to M-Files - we don't want images from email signatures!

We are using the classic Outlook desktop client.  We have the M-Files add-in bar at the top of Outlook.  If we use the option, from that bar for Save Attachments to M-Files, when the email saves, every graphic that's included in signatures within the email, is saved as images in the vault along with the attachments.  We just want the attachments, but not the images from the email signatures.  How have others addressed this?
