Global settings?

Is there a way to create a set of global settings/defaults for Spongecell -- i.e, a way for the form to auto-populate with the address of our church for every event unless I change it to something else? (Most of our events are held at the same address.)

Also, is there a way to edit the event page settings for ALL the pages at once? (Some kind of global settings that will affect all pages - if I decide to change the color and don't want to have to go through and change each individual event page?)
