Yes, Not clear exactly what you are trying to do. I think it is a linked file but here are some options:
Global Edit
A gobal edit, if the artboards reside in the same file, can globally change similar objects at once. This is for a specific object
Symbol
If you are using the same content in a document and it is made up of many objects then we are talking about a symbol. Just create a symbol out of the graphic. Then when you update the symbol all uses with be updated too.
