Page title of category

[mrlunacy]

I have following menu structure on my page:
main
>> sub1
>>>> sub1.1
>>>> sub 1.2
>>sub2
>>>> sub 2.1
>>>> sub 2.2

So problem is that name of sub 1.1 is the same as sub 2.1
So when I click on category sub 1.1 I have page title: sub 1.1 - shop name
The problem is that when I click on sub 2.1 i have the same page title.
How to change page titles that they will be generated automatic with following patern:
for sub 1 page title: sub 1 - shop name
for sub 2.1 page title: sub 1 | sub 2.1 - shop name.

In your BO go To Catalog, and edit name of category and sub categories there
