MVC3: Grouping Action Filters or calling Action Filters from other action filters

[xccdark]

I'm trying to write an attribute class that can be used on all my "admin" actions which then effectively applies all relevant action/auth filters to that action. For instance, I always apply the \[code\]AuthoriseAttribute\[/code\] and a custom \[code\]AdminLayoutAttribute\[/code\], so my intention is to just have an \[code\]AdminAttribute\[/code\] which somehow implies both the above. That way I can make changes to the entire Admin section in one handy place. However I don't see how I can do this. Can any one point me in the right direction?Much appreciated.
