    Nearly possible to do that with worklists.

Worklists are too inflexible--they specify a particular order for
building things.  What I would like is simply to find out which
cities lack this or that.

The F1 -> Select feature, which I did not know about before, does the
job somewhat, but not perfectly.  If it had a way to select cities
that have X, Y and Z, then I could do so and invert the selection and
get the list I want.  If I could also do boolean operations, and
select based on what is currently being built, that would get all the
way there.

It would be nice to have a feature to specify a selection criterion
and then say "notify me each turn about cities that meet this
criterion."
