Select all type in layout?

I keep having the need to change the properties of every instance in the layout. At the moment I have to go to the project bar, find the object and click on it.

Is there a shortcut having one selected object, to either select all of the same object in the layout or select the object in the project bar?

If you go to the project bar and select the object then it selects all instances in the layout and you can change them all at the same time, problem solved?

Nope. Please read the full post.
