I have 1 magento installation with 2 websites. i want to set a subcategory from website 1 as rootcategory of website 2. and i don't know the id of the category, because this is local and has to work on production with other categories. So i can't set the id of the wanted category in code. it must be adjustable in the backend. in system-manage stores- select a store here you can set the rootcategory but there are no subcategories available. is the only solution to build a module to select the id of the category?
