if you only have a few days your looking at and you can control the values in them (of a param or todays date) you might consider
grouping on the employee
making a series of formulas as if-then for each day
//today
if {table.date}=currentdate then {table.date}
//yesterday
if {table.date}=currentdate-1 then {table.date}
now do a maximum of each of thes e formulas at the group footer
drag the naem into the GF, do a sum of hours at the GF
suppress the GH and details
another option might be a shared variable to conactenate the dates togtehr but this will be read as 1 field in the export, not many fields.
