Instance Names & AS

I was wondering if there was a way to classify multiple instant names under one variable.

For example

my_cities = atlanta, boston, tokyo, la
my_cities being the variable.
atlanta, boston, tokyo, la being the instant names.[/SIZE]


my_cities._alpha = 50;

^ & all of the instant names under the variable “my_cities” would be effected. I could use some help on finding the right AS lingo to make this work.

I’m asking because I’m making a map with lot’s little pin points where the cities are… & a super big time saver would be being able to affect all of those pin points (cities) at once.
