Text Table Question

Hello All,

In my text table, I have a field named "Annual Projection" (This field is calculated in my transformation process prior to being loaded into Tableau).

Question: I'd like to ONLY show the Annual Projection field as 'Grand Total'. Please refer to this screenshot to see what I mean. I do not want the field to display for each month's aggregation.

My packaged workbook is attached here as well, if that is helpful. I am stumped. Any help would be greatly appreciated!

Thanks in advance for any assistance!
