[TYPO3-commerce] Subcategories in a seperated menu

[H.E.Weenink | Aristo WebDesign]

Dear People,  I have commece running and categories show in a nice menu,
with many thanks to you all. 
Next step is to show subcategories on a different place on the screen. When
doing pages-menus I would use entrylevel to get rid of toplevel.  but....
this does not work on userfunc menu.  How to get this done. Below the
typoscript (I use TV) what I used uptill now, but the SubCategoryMenu  keeps
showing ALL categories.  Is it possible to feed the SubCategoryMenu  with
information of the CategoryMenu or something like that? 
Must be a problem some of you allready solved before. Please help, Regards,
Eef
