Is there any way to turn off signing-off of imported items?

My inbox gets overloaded by requests to sign-off items which don't need to be signed, such as patient's insurance cards, EKGs, Xrays and other scanned reports which have already been signed by me on paper.

We are completely paperless. Office employees scan on average 10-15 items per hour. I have to interrupt my work every 2-3 hours to clean up my inbox because it becames so crowded by this junk mail making it difficult to find forwarded patient charts.
