Blocklayered depth settings

[Vire]

Hello there,

 

i have a short question but i cant find the .tpl or what ever data i need so i need your help. 

 

I like the navigation quite a lot but the depth of 3 categories is too much.

for example the "Computer" menu. All the 3. Categories destroy the navigation a lot. Its enough if the customer can select one of the 2. categories and than choose deeper by picture or the following selection on the top left like here:

Is there any way to delete something out of the Blocklayered module datas so that it only show 2 categories deep and not all of them?
