Add Vertical Line to Line Chart based on one Value

[dwel0120]

I have a line chart consisting of two categories. The x-axis contains dates (as texts) and the y is an average probability. I want to add a vertical line (red dotted line) to the chart based off of a value from a column (10/1/20). The column has one value for all rows. I can't insert a red line at 10/1 because I have several slicers attached to the visual that will cause the dates to move around. Any ideas or workarounds?

Please watch this video to learn how. Instead of setting measure to "7", you can set it to the MAX value of the data so that it always goes to the full Y axis.
