Is the number of sales rep (7) a known value that will be fixed ?
If so, the above solution will do what you want, you will just have to duplicate it, once for each sale rep (your app in in read-only mode so I can’t do it for you, but try it should work)
Look at it, I did it for #6 and #7 only.
It is a bit tediuous to do but it should work
I would also recommend that each “Do a search for Sales Rep” you do is sorted by unique id to be sure the list is always in the same order
I mean that each search called “Search for Sales Rep”, the one for the name, and the one inside the search for calls, should be sorted by unique id.
Maybe I am paranoid but that way you are sure that hen you call item #7 to display the name, this is the same item #7 you get in the search for calls…
