There isn't a way to link the same symbol attribute between multiple symbols is there?

If you make a symbol of the text attribute(s) you want to share, then you can nest it in other symbols.

I think what you are asking - is to have a "master" attribute that is linked to all the other instances.

By nesting things, you could get that - by having a different symbol for each value. It wouldn't be an attribute (my mistake), though - just a text entity, that you edit in a drawing, and all the instances change when you edit one of them.

You could look into using a Lookup field and Field filled by Lookup, using a database. Then by editting the database for that project, one could change the attributes in the many symbols link to that database.
