I'm looking for a shortcut to updating my drawing numbers located in the sheet layer as a note. Currently I have to go into each drawing, edit the sheet and make sure it is the correct drawing number. This isn't a huge deal but I think it could potentially be unnecessary since the name of the drawing file begins with the drawing number. For instance, the filename for the drawing shown below would be "D13 - PIVOT PLATE COMPONENTS". Is there any way to link the "D13" note in the drawing, which I am currently manually editing, to the first three positions in the string of the SW filename? Is there an alternate solution to this?
