Hello
I have spend few hours and I ave lost.
The problem is as follow:

I have pivot table grouped
Group I
    ...items
    ...items
Group II
    ...items
    ...items

When new item appears:
Group I
    ...items
    ...items
Group II
    ...items
    ...items
new item

The problem is how to add "new item" in to existing Group, becouse  when
I try to add item to the group the new group is created.

regards
Peter
