Knock yourself out. Here is the essential code manually applied from the console:
$("label.fieldLabel b").filter(function() {
return $(this).text() === "alpha";
}).text("ALPHA");
$("label.fieldLabel b").filter(function() {
return $(this).text() === "beta";
}).text("BETA");
The four fields are
[alpha], [beta], [gamma] and
[delta] as show in the report.
You of course would not be substituting the appropriate month for the label not capitalizing the field name. Easy to do but I assume you are going to abandon this idea.
