AutoCollapse Item (based on a condition)

[#1]

Hi all, one question not too simple to explain. I have some pivot chart with a tree structure:

A: 8 (5+3)
Aa: 5 (1+2+2)
Aa1: 1
Aa2: 2
Aa3: 2
Ab: 3

B: 1
Bb: 1
Bb1: 1

C: 11 (7+4)
Cc: 7 (3+4)
Cc1: 3
Cc2: 4
Cb: 4 (1+3)
Cb1: 1
Cb2: 3

now.. that's a normal pivot... but I have also some level calculated starting form other ones (eg.: D = C-A-B) for which I created the single row multiplied per +1 or -1 depending on the sign.
Every record created has a flag set to 1 that indicates that this is a calculated record. In this way I can recognize them. So in the pivot table where the sum of this flag is >0 I can put the description of the level and his value in BOLD.

It works fine, but now I want to collapse automatically the calculated level (the D level in this case), cause when I design the pivot the D level is expanded per default, like the other ones. So I have this situation:

A: 8 (5+3)
Aa: 5 (1+2+2)
Aa1: 1
Aa2: 2
Aa3: 2
Ab: 3

B: 1
Bb: 1
Bb1: 1

C: 11 (7+4)
Cc: 7 (3+4)
Cc1: 3
Cc2: 4
Cb: 4 (1+3)
Cb1: 1
Cb2: 3

😧 2 (11-1-8) [Line Calculated, below all the addend expanded per default]
Aa: -5
Aa1: -1
Aa2: -2
Aa3: -2
Ab: -3
Bb: -1
Bb1: -1
Cc: +7
Cc1: +3
Cc2: +4
Cb: +4
Cb1: +1
Cb2: +3

There's a way to do this for example with a macro? I've tried with "ExpandLeft" and "CollapseLeft" but my fault is that I cannot tell to QV the items that have to be collapsed and the ones that should remain expanded.

This is the result I want to obtain:
A: 8
Aa: 5
Aa1: 1
Aa2: 2
Aa3: 2
Ab: 3
B: 1
Bb: 1
Bb1: 1
C: 11
Cc: 7
Cc1: 3
Cc2: 4
Cb: 4
Cb1: 1
Cb2: 3
D (Collapsed): 2

I hope it's clear.

Thanks

Some ideas?
