The highlight changes feature is fantastic...however, it would be very nice if you could set an "as of" date/time. For example I created a SmartSheet today and sent it to my team for feedback...I can't use the highlight changes now because everything I did initially shows up as a change. If I could set a date/time as of my last edit, then antyhing contributed since I did my initial work would be highlighted. As I'm only using this for a couple of days at most...the highlight changes won't be of a lot of value. I can, of course do conditional formatting to achieve this, however I would like to see an enhancement to support this.
