Dynamic grouping(count) based on Row no on different selection (Dimension) in Qliksense 2018

[AC7]

Hi -

I have a table with the data below. 

Item	Category	Style	Item status	Retail price	Qty
A	AN	Curve	Active	100	1
B	AS	Round	InActive	200	5
C	AD	Flat	Active	200	6
D	AS	Round	InActive	300	7
E	AD	Flat	Active	400	8
F	AE	Round	Active	600	22

If I select 'AD' from Category and 'Flat' from Style I get this (adding row_no dynamic based on different selection critieria)

Item	Category	Style	Item status	Retail price	Qty	Row no
C	AD	Flat	Active	200	6	1
E	AD	Flat	Active	400	8	2

Now, my requirement is to create a pivot table like this from the above table:

	A Grade	B Grade	C Grade
Condition (Row no)	<2	>1 and < 4	Others
count(Qty)	1	2	0

Any help would be much appreciated
