pause macro for cursor placement on graph

Is there any way to pause a macro for cursor placement on a graph?

I don't want a timed interval (e.g. 10 seconds), but rather, place several cursors using the image tools, and then resume a macro that calls upon the values of those cursors.

I was thinking of "Sleep" but then I saw: 

"The Sleep operation does not let the user select menus, move cursors, run procedures, draw in graphs, or do any other interactive task."

- thanks for any guidance.
