Looking for an object to reference using EL that would allow me to specify the specific document where I would like to see the change

Hi Everyone,

My client has a requirement to change the name of the 'Employee Comments' field on the Overall Summary section. However, this field is a shared component, meaning that if I change it on this document, it will change for every other performance document with an Overall Summary section. I am trying to find some logic that I can put into Expression Language, that will reference the specific document or template being changed.
