How do I link Blocks and make them auto update?

[neuri]

I know you can link Excel sheets to a drawing.

 

And when I make a change in the excel file, I just have to open the drawing and click "Update tables".

 

Is there a similar thing for Blocks? I got some blocks of chairs/freezers/shelves that I want to insert and when I make a change, it auto updates whenever I open the drawing, is this possible? It would save me a lot of time.  Only way I can find is to re-insert the block and Redefine it, is there a way to do it automatically or a simple command to redefine all blocks?

Perhaps the problem can be handled in another manner.  I'm thinking either by inserting blocks as an Xref or by creating Dynamic Blocks.
