Question : Pivot statement with Dynamic SQL and totals columns

The atteached code, supplied by an EE Expert works great.

The data is output as:
rep January February etc
myrep 1000 1250 etc

Question...
Is there a way to add a totals column and if possible an average per month column?

New output desired...
rep January February etc Totals AVG
myrep 1000 1250 etc 2250 1125
