Call all instances of a symbol

Question

Hej,
i need to place 10 different kinds of symbols, a hundred times each on my stage. Theses symbols have the same shape, but different colors. I need to filter them out in a tiny top-menu.
So, if i click e.g. on a red circle, i want all non red symbols to set there opacity to 0.5.
It could be simple if i place all red symbols into a container "$color-symbols" and set the opacity to them. But that is not possible, because I need to place each symbol manually. And if they are childs of another symbol, drag and drop is horrible.
Now i am wondering if it is possible to call all symbols on stage that are instances of a symbol in my library.
And is there a nice way to call "all-other-colors" instead of
sym.$("color-1").animate({opacity:0.5},500);
sym.$("color-9").animate({opacity:0.5},500);
sym.$("my-own-color").animate({opacity:1},500);
on every button on stage?

Thanks for your help,
i use the classes to specify a target url for each symbol.
For Example:
I have three red symbols and three blue symbols.
The classes for the red-ones are:
33451, 56789 and 45678
for the blue ones:
983, 4, 1002
Inside of my symbols i have a script:
var names = (e.target.id).split("_");
var page = names[2];
var link = "http://www.url.no/subpage/"+page;
window.open(link, "_self");
If i find another way to put a specific ID (and it must be a number) on to each Instance, i could use the way you describe.
Because your idea is to use the class-names, there is no way to call all instances of a given symbol?
Is it possible to use wildcards for my array?
So i could name them "red-33451#1", "red-56789#2", "red-45678#3". And cut out everything between "-" and "#".
But remember that i need to place a few hundreds of them, which isn't fun. And if i need to insert one later or if i delete another one, i need to verify all my functions.
