Section view note

Hi,
In one of my drawings having a sectional view, the note below theview "SECTION A-A" is missing (Deleted by mistake).
I have tried adding a note having the same properties, but thisnever updates if the Section name is changed.
a) Is there a way to get my original note back (The file has beensaved many times)?
b) If I insert a new note how do I make it associative to theSection name so that the note changes when the Section name ischanged from A to B?SolidworksDrawings And Detailing
