Cell Value Minus -? Is this possible in Smartsheet

I am working on a pretty massive data sheet and I have 4 years that are broken down by Months and then by Days of the Week.


=SUMIFS({Resources_Required Data}, {Group_Name}, $[Primary Column]$197, {Weather Data}, $[Primary Column]$214, {Day of Week Data}, $[Primary Column]215, {ADD_TIMESTAMP Data}, >=DATE(2016, 1, 1), {ADD_TIMESTAMP Data}, <=DATE(2016, 12, 31))

What I have been doing and will probably continue to do, unless I get a reply with a great suggestion, is copy Sunday through Saturday into my sheet and then go through the first cell of each column and change the $[Primary Column]$214 to 1 number less than $[Primary Column]215.


I'm trying to find a way to do this automatically as the cell that I'm capturing data for the $[Primary Column]$214 is the Month.  

Is there a function or formula that I'm not thinking of that can automatically grab the cell data that is 1 less than that of $[Primary Column]$215

Sorry if I'm not being clear, I can describe more or show an example if needed.
