Hi Kennie Harris,
You can make a simple app to support this workflow using Web AppBuilder, the Draw and Analysis widgets, and a web map with a map notes layer in it. It's not a one-click workflow, however. Using these components, the user would need to perform two steps using the draw widget and the analysis widget. First, they would use the draw widget to create a point of interest using the map notes, and then, using the analysis widget, you would configure the widget to run only the drive-time analysis tool, and the user would then select the name of the map notes layer to run the analysis against...its not a perfectly clean workflow, but its something you could put together quickly to support that particular workflow need. Hope it helps!
Chris
