Setting Macro Security Level in Office 2k7

Can it be done? Like the old Hi med low?
All I can find is to either setup a trusted locations and turn macros off unless its a trusted location, or allow all macros.
I know you can set it to disable all macros w/ message and let the user choose whether to enable them or not, but I was looking for a way to set the Level of security on Macros.

Thanks!
