Show groups like a tree

Hi,
i have got a dataset like this:
Section Subsection ID Name
01. Category --- 101 cat1
01. Category --- 102 cat2
01. Category 01.Subcategory 01101 subcat1
if i group first by section, after by subsection, the result is this:

01. Category-------------group1
01. subcategory-------group2
id:01101
name:subsection
but i can't see the id and name of section category 01. category, because i can't put a detail line between group1 and group2. is there someway of see results like this?

01. Category-------------group1
id:101
name:cat1
id:102
name:cat2
01. subcategory-------group2
id:01101
name:subsection
thanks
