Is there a way to get the current viewport (date/time range) of a scheduling gantt chart?

I have a workshop with two scheduling gantt charts, and I am trying to sync the view when a user scrolls on one of them. Both charts use the same variables for the timeline start and end timestamps as well as the custom display range start/end timestamps.

Looking for a way to sync the views when the user scrolls on one chart.

I tried to use a right-click on the the resource row to capture the date/time of the click, but the Selected Start Date workshop variable only seems to be available on actions (not events). If I could save the date/time into a variable on a right-click, I could get the two charts to sync.

Better yet, if I could somehow retrieve the dates from the header… e.g. -

Are those stored/accessible?
