[Rails ] inheritance template w namespace ..

I have been using template inheritance wo any problem

I have defined an :admins namespace ( used w Devise
authentication) , so I have controllers defined in admins

/admins
    /sessions_controller
    /plans_controller
    /categories_controller

In my 'administration' layout I am using a partial
#side
   = render "side"

I can define this partial in :
views/application
views/admins/plans
views/admins/categories

I wonder if I can have a partial at the namespace level ? I can
defined it in a shared folder
views/application
views/admins/shared
views/admins/plans
views/admins/categories
.. but the I'll have to write = render "admins/shared/side" in the
layout , and views/admins/plans will not inheritate

feedback welcome
