Yes, with a little qlik foo in the script. You can add an extra table that creates a new field to link the VC values to the totals.
LOAD * INLINE [
ReportField, FIELD, IsTotal
VC1, VC1, 0
VC2, VC2, 0
VC3, VC1, 1
VC3, VC2, 1
VC4, VC4, 0
VC5, VC5, 0
VC6, VC1, 1
VC6, VC2, 1
VC6, VC4, 1
VC6, VC5, 1
Then use the field ReportField as dimension in your pivot table instead of FIELD.
You can use the IsTotal field to change the background color of the total rows and to change the text format to bold.
Click on the + in front of the expression, select Background color and use =if(IsTotal=1, LightGray())
Click on the + in front of the expression, select Text Format and use =if(IsTotal=1, '<B>')
Do the same for the dimensions.
