Show groups/subgroups and counts under content types in faceted guided search

hi,
Can we make groups/subgroups names and counts come under content type upon clicking content type,and also varies according to search.

something like this..

Guided search Block

Content type

* Blog entry (8)
* Groups (4)
* Page (1)

when i click on Groups it has to show like this..

Content type

* Blog entry (8)
* Groups (4)
*Group1(1)
*Group2(3)
*Sub Group(2)
*Sub Group(1)

* Page (1)

It should also show subgroups in search..

Thanks in advance.. :-)
