If you go to Program Files\Solidworks\lang\english you will find a file named Gtol.sym. Open this in Wordpad and make a copy in case of errors. Add the following to the Modifying Symbols :
*LE,Less Than-Equal To
A,LINE .0,.5,.6,.8
A,LINE .0,.5,.6,.2
A,LINE .0,.1,.6,.1
*GE,Greater Than-Equal To
A,LINE .0,.2,.6,.5
A,LINE .0,.8,.6,.5
A,LINE .0,.1,.6,.1
Then close SW and reopen. Voila! there are your symbols for notes. I think that you'll have to add this to all your seats, and I'm not sure if it will email correctly, so maybe you should check on that.
You can also rearrange the symbols to correspond with frequency of use.
