So the times across the data sources would need to be an exact match for the rows to be recognized with the existing fields but you could aggregate the selections to a level that makes sense for both data sources. Something like the call within that hour or minute. I have updated the view so that selecting one of the calls highlights all of the application timeline for the same hour.
I hope this helps.
