From CS6 upward InDesign has the content tools.
Select an item with the content collector, then you see the convoyer, there you can change to the content placer and activate the option to link.
Later you have to edit the original and update in the link panel all instances.
It can also be done in several documents.
I forgot to mention that I'm using CS5.5.
Create a master document that is the size of one sticker. Place that into your sticker sheet file and use Step and Repeat to fill the sheet.
You can edit the master file and update the links in the sticker sheet file.
