Using Date from other cell as an email trigger

Hello all,

I am currently trying to send an automated email to a target person once a certain date assigned to them is reached. As of right now, I only see triggers for when a date is an exact date, but it must be the same date for the whole base, and not dynamic per each certain date that is unique to each target person. 

Simplified: I need to set a trigger for a date that is set for individual rows, is this possible?

Thanks!
