Is there any way I can time stamp the most recent time/date when a lead responded to our campaign?
That field will be overridden to the most recent activity.
So, say if the lead filled out our form on 10/15/2016, the time stamp should be 10/15/2016. However, if the lead recently attended our event on 12/10/2016. Then, the time stamp field needed to be updated to 12/10/2016.
Is there a way to do that?
