Toolbar category filter

I'm having 5 categories in easy discuss, out of which 4 are closed categories (i.e users are not allowed to start a new thread in these categories, they can only post replies)

Now if the toolbar category filter is enabled only those categories which have new post new thread permissions are show, categories without post new threads are not shown)

Is there any setting wherein all categories are shown in the Category filter irrespective of the ACL.

regards
Sunny
