How can I save different values in different fields of my structure?

I have a structure and I want to pull temperature data for specific dates. I wrote a code that loop trough the structure, but my idea was to created another structure that save those specific values. Because more than one field of my structure has temperature at the same dates and I will like to keep track of where those values where/ Right now is saving everything in one variable called A.

Here is an example of my code:

timeofproject ={'07192013','09062013','03272014'};
copy = mooring; %This is my structure
month = 3;
day   = 1;
year  = 2014;
l=1;

 for i = 4:-1:1;

     for j = 1:length(timeofproject);
         for ii=2:4;
         fieldName = fieldnames(copy.(['T', num2str(i)]));
         fieldName = fieldName{ii};
         fieldName = fieldName(6:end);
         for jj = 1:3
            if fieldName == timeofproject{jj}
                break
            end
         end
         pCount = fieldnames(copy.(['T', num2str(i)]).(['data_', fieldName]));
         pCount = length(pCount);
         for k=1:pCount;
             [m,n] = size(copy.(['T',num2str(i)]).(['data_', fieldName]).(['P',num2str(k)]).Data);
             for kk = 1:m;
                  if (copy.(['T',num2str(i)]).(['data_', fieldName]).(['P',num2str(k)]).Data(kk,3) ==  year) & ...
                     (copy.(['T',num2str(i)]).(['data_', fieldName]).(['P',num2str(k)]).Data(kk,1) ==  month)& ...
                     (copy.(['T',num2str(i)]).(['data_', fieldName]).(['P',num2str(k)]).Data(kk,2) ==  day);

               A(l,1:7) = copy.(['T',num2str(i)]).(['data_',fieldName]).(['P',num2str(k)]).Data(kk,1:7);
                  l=l+1;
                  end
             end
         end
         end
     end
end

Thanks
