Animation and symbols

Hi everyone

My problem is that I have alot of symbols in my file and now the file is so big, that it gets kinda messy - my fault that I didn’t gave the symbols names from the beginning.

What I want to do now is to edit a particular symbol, but I am not sure if the same symbol is in the other scenes.

Is there a way to get some kind of graph, that tells you how many times this symbol is used and where?

Thanks
