I have 2 questions:

1) I want to add a widget with secondary value of AVG. 

Ex: 

Store 1: 50000

Store 2: 23000

Store 3: 10000

The average revenue here is 27000

So I want to show the next value 50000 (up 92%), because it is 92% better than the average 50/52

How do I do that?

2) I want to use Avg in my calculation in pivot table, like instead of show total sum, I want it to show total average of the column. And then I need to add a formula of calculating the % of each value from the average. See ex below

		% of total	% of average
Store  1	50000	18%	127%
Store  2	43000	16%	109%
Store  3	24777	9%	63%
Store  4	54666	20%	139%
Store  5	37777	14%	96%
Store  6	25788	9%	66%
Average	39334.66667
Total	275342.6667

Thank you in advance!
