Categories in multistore

[ale-youco]

Hello, I've a question about the category management in a multistore enviroment.

I have several categories (about 500) with a very big and complex treeview.
I have several store, every one can select wich categories should use and eventually modify his treeview.

But every times a store edits a category (status visibile/not visibile or parent category) the change is reflected in every store of the environment. A store can only edit Title and description without having impact on other stores.

In the db in fact there is only one - simple - table called "category" without any reference to shop id.

Is there a way to avoid this?

I hope to have been clear
