Thanks guys.
Andrew - the alert can go out whenever, we don't want the lead to be re-assigned to someone else out of business hours. E.g. If I am a west coast SDR and a lead comes in at 8:30 PM, an alert goes out to me. Cool, no problem. If no activity happens by 9:30 PM, I don't want the lead to be reassigned to someone else. However, the next day, if not activity has happened at 9:00 AM, then I do want it reassigned to someone else. I want the flow to execute within a time range and pause activity until that time range begins.
Does that make sense? Any other ideas how to do this? Thanks!
