I do not know of a way to do that between drawings. If you added the note as an annotation to the model such that it would show in a particular configuration and then had that view on the drawing import that annotation it might approximate what you are looking for. In general, the info on a drawing pulls info from the model, not other drawings.
So like configurations, but with drawings? Interesting idea, but you can't do it.
What you could do is a "File, Save As" after making changes to the original drawing, and then right click on the views and "Replace Model" (you could also use Solidworks Explorer Or PDM to this I believe).
If the file names are the same like in your example (generally considered a gigantic no-no), you could simply drag n drop the drawing file to the new directory and it will load up the local version of Part1.
I'm create a model and detail drawings for a customer. The model has a bunch of options like in my example with wheels or with out wheels. To keep everything simple for them when it comes time to print the details I was going to create a folder and under the fold have the whole set of details. This is why I want multiple drawing with the same file name and why I want them to update each other. What I might do is create a folder for all the "standard" prints and then create folders for the options they want.
Thanks for the input
