Icons for ID and Renters agreement in calendar ribbon

We go through daily to see if our guests have signed the renters agreement and provided ID. 

What if there was a way to visually see if an ID has been uploaded and Agreement has been signed. The idea is to place an Icon(s) in the ribbon that indicates the renters agreement and ID have been provided. I have attached a basic image of an idea. 

Great suggestion!  One tip - you can filter the ribbons calendar (using the Bookings filter button at the top) to see which ribbons have "renter agreement signed" versus ones that don't.  That's not quite a cool/convenient as your icon idea, but just pointing it out in the meantime!
