Add Headers to Swipe Tool's Imagery Viewer for Clear Year Selection

[AyeletGreenberg]

It would be helpful to add headers to each side of the imagery viewer app when using the Swipe tool.
I configured the app using aerial images from four different years, so the users can select which year to view on each side of the swipe slider.
A header showing the selected year on each side can help the users remember which years they chose for which side. (See suggested example below).

I know that users can keep the imagery viewer/selector open to see the selected images, but it covers part of the screen.
