My application is made up of several modules, so that they can be independently placed on the page.  Each one requires individual configuration with a parameter, the parameter will have the same value for all the modules on the page.  This manual configuration is somewhat error prone; it is posible to configure two modules on the same page differently.

Is there any established practice in this area?  It seems to me that a parameter configurable at the page level and available to the modules on the page would be a great fit.  If such a thing exists I am not aware of it.  Any other suggestions?

Thanks Bill,

It's somewhat imperfect, but *way* better than any other ideas I had.  For my purposes I'm OK with managing it from my module settings control, with a message pointing out that the setting is (potentially) shared by all modules on the tab. 

I'm OK with taking a DNN 5.02 or above dependency.
