Questions regarding showing cells in different colours depending on value within a Matrix

Hi

I have a few questions regarding Microsoft SQL Report Builder. 

The monthly fees report includes a section stating how much we have billed for the month it was run so say in this instance 82k it also shows the same month for the previous two years. Can we show them figures (76k and 68k) in black or red depending on if they are more or less than the current month total?

Report can be viewed here to show the layout and figures.

This would be a visual indicator to say it the department has performed better or worse this year.

The fee report also takes a long time to run due to the amount of datasets within the report and I was wondering if I could reduce that amount with more generic datasets that are then defined within the matrix?

For example I currently use the following for one dataset

SELECT
  Practice.ibvStaffCategorisation.StaffId
  ,SUM(Practice.ibvStaffTime.NonChargeableAmount) AS Sum_NonChargeableAmount
  ,SUM(Practice.ibvStaffTime.NonChargeableMinutes) AS Sum_NonChargeableMinutes
FROM
  Practice.ibvStaffCategorisation
  INNER JOIN Practice.ibvStaffTime
    ON Practice.ibvStaffCategorisation.StaffInternalId = Practice.ibvStaffTime.StaffInternalId
WHERE
  Practice.ibvStaffTime.Activity IN (@Holiday)
  AND Practice.ibvStaffCategorisation.StaffId IN (@ABSStaff)
  AND Practice.ibvStaffTime.[Year] = @Year
  AND Practice.ibvStaffTime.Period = @Period
GROUP BY
  Practice.ibvStaffCategorisation.StaffId

I then have another dataset

SELECT
  Practice.ibvStaffCategorisation.StaffId
  ,SUM(Practice.ibvStaffTime.NonChargeableAmount) AS Sum_NonChargeableAmount
  ,SUM(Practice.ibvStaffTime.NonChargeableMinutes) AS Sum_NonChargeableMinutes
FROM
  Practice.ibvStaffCategorisation
  INNER JOIN Practice.ibvStaffTime
    ON Practice.ibvStaffCategorisation.StaffInternalId = Practice.ibvStaffTime.StaffInternalId
WHERE
  Practice.ibvStaffTime.Activity IN (@AgreedLeave)
  AND Practice.ibvStaffCategorisation.StaffId IN (@ABSStaff)
  AND Practice.ibvStaffTime.[Year] = @Year
  AND Practice.ibvStaffTime.Period = @Period
GROUP BY
  Practice.ibvStaffCategorisation.StaffId

And the only thing that changes is the Pactive.StaffTime.Activity IN. What I was hoping to do is create a generic dataset and then have the cell within the matrix that only showed Practice.ibvStaffTime.Activity IN (@AgreedLeave) for the “Agreed Leave” column and likewise Practice.ibvStaffTime.Activity IN (@Holiday) for the “Holiday” column.  I think the answer will be no but I thought it was worth asking in the hope of reducing the time it takes to run the report.

Any advice appreciated.

Cheers Chris
