Dear Padma,
For the first level of analysis, consider 'Hit Depth' Dimension in WorkSpace.
If the User Journey is Page1 - Page 2 - Page 3 - Page 4 then Page 1 = Hit Depth 1, Page 2 = Hit Depth 2, Page 3 = Hit Depth 3 and Page 4 = Hit Depth 4.
If you still want to understand the exact second, then you can use the Data Feed option for the hour to see the raw image request details.
Thank You, Arun.
