Contextless Actions

Is there a way to assign a default Context to an Action? This would be very helpful in some situations:

A) Prevents overlooking accidentally contextless and therefore disabled actions. I often forget to assign a context, especially when creating a dozen or so actions in a row, so I have to remind myself to constantly review all of the kGTD content looking for contextless actions.

B) Like the ‘Unfiled Actions’ list for assigning actions to projects, a contextless actions list can be used to encourage assignment of actions to contexts.

C) When most actions fall into a single context, using that context as the default would save time.

D) It would probably fix a previously-mentioned discrepency when syncing back and forth with iCal where tasks disappear because they don’t have a context assigned.
