Check in and Check out times for automated tags

We would like to be able to automatically tag if someone wants early check-in or check-out or if we change the time the guest checks in or out and it automatically tags it. 

Great idea 

This is an awesome addition 

Yes, this is what would make this upsell a more automated feature. I currently have an tag automation for pets which then I use to trigger an email to remind our cleaners to set out the pet gear. I would like to do the same for early check-in/late check-out.
