Lock annotation to a specific X-Axis value?

I have a line chart with dates on the X-Axis and values on the Y-Axis. A zoom slider is used to visualize different timespans of the data. I would like an annotation that stays locked to a specific date, so when the zoom slider is used to view different segments of data, the annotation does not move off of that date. I feel like this is a tall ask, but figured I would see if anyone had a solution?
