Add columns for custom taxonomy in admin

Hi..
In Wordpress 3.5 there was added a new optional argument, ‘show_admin_column.’

From the codex:
show_admin_column
(boolean) (optional) Whether to allow automatic creation of taxonomy columns on associated post-types.
Default: false

Is it possible to set that argument to true, for a custom taxonomy in CustomPress, or how do I do it..?
