Easyarticle : Restric publications in one categorie

Hello,

Is it possible to restrict categories selection on easyarticle for membes ?

i use jreviews and its using many joomla categories, for easyarticle i need to set up unique category and let members post inside it. I need to block publication in other categories to avoid conflict between both extension.

I think thats possible if i change categories ACL but the problem is that members will not be able to post throught jreviews.
