Your guidance helped...I think I was trying to make things too complicated, as I had built a dozen templates. Using your approach it was only three and then while your approach resulted in multiple records for each Cost Center, I was able to sub-total each cost center with a Summary. Perfect example of a time when I needed to apply the KISS principle:)
If you only needed to use the totals & match them to the cost center, you could use the total line as a detail & append the cost center info & not pick up the (work station?) lines.
However this takes away from the fun of using Monarch's summaries were you can have both the details & summary.
