Insert rows alternatively in Pivot Table to calculate percentage of fixed ranges

[acsishere]

Dear Friends,

I have a pivot table like this:

		QUALITY POINTS								
ITEM	COMPANY	A1	A2	B1	B2	C1	C2	D1	D2	TOTAL
HANDYCAM	A	12	4	2	2		2			22
	B	3	5	9	4	3	9	3	1	37
	C	11	3	4	2		1			21
	D	13	9	2	4	1	2	3	5	39

I need to insert a row alternatively to do a percentage calculation of each quality points, as like below:

		QUALITY POINTS								
ITEM	COMPANY	A1	A2	B1	B2	C1	C2	D1	D2	TOTAL
HANDYCAM	A	12	4	2	2	0	2	0	0	22
		54.55	18.18	9.09	9.09	0.00	9.09	0.00	0.00	100.00
	B	3	5	9	4	3	9	3	1	37
		8.11	13.51	24.32	10.81	8.11	24.32	8.11	2.70	100.00
	C	11	3	4	2	0	1	0	0	21
		52.38	14.29	19.05	9.52	0.00	4.76	0.00	0.00	100.00
	D	13	9	2	4	1	2	3	5	39
		33.33	23.08	5.13	10.26	2.56	5.13	7.69	12.82	100.00

Is it possible to do like this in pivot table? If NO, any alternate method to accomplish this target? The items / company columns in my table frequently varies. Hence I am unable to refer the pivot table cells in any other sheet.

Any help is highly appreciated.

Thanks in advance.
