Table scope -- specify owning context

Let's say we create a table. If we want the table scope to be the elements inside the package or other element that owns the diagram, we can select or drag that package or other element to the table scope field (the Containment query).

OK, now let's say we want to create many of these tables, so we do not want to update the scope each time.

If we copy the entire context, the scope updates automatically.

If we just copy the diagram, though, to an existing context, the scope of the diagram is still the old context.

Is there a way to specify that the scope is the (immediate) context in which the diagram resides? (The other 2 options -- Structure query -- which works similarly to the Containment query -- and Custom query -- do not seem to help here, or at least I have not found a way yet to make them helpful. My understanding is that the Custom query does not start "here" (i.e., with the table), but you have to define the place to start somehow.)
