Filtering in custom templete report

[Joshsbk]

I set up a email report for the work one employee does in a day it lays out like this:

Employee: Joe
[Start]
[Customer]: [Work Requested]
[Work Performed]
[End]

I would like to make this usable with multiple employees now but im not sure how i set up the filtering for it. I would like it to lay out like this:

Employee: [employee] (Joe)
[Start]
[Customer]: [Work Requested]
[Work Performed]
[End]

Employee: [employee] (Harry)
[Start]
[Customer]: [Work Requested]
[Work Performed]
[End]

I also would like to place certain [customer] rows in a specific order but cant wrap my head around how to do that.
