Numeric Symbology

[JeremyNeufeld]

I'm trying to make a map layout for printing for a hazard analysis.  Our emergency coordinator wants the points on the map identified as numbers and then have the legend list what each corresponding number is for.  Is there an easy way to do this?  I can create a label style for this however I'm not aware of a way to translate this to the legend.  I can manually create symbols with a number in them using the font option however that give me a single character up to 9.  I can't add items beyond that.  Are there any suggestions on how I can approach this?

Like text symbols but with numbers in them as in the highway shield example

maybe that is the route to go.

I had previously looked at that article.  From what I gather I can use that for labeling which would address the 1 challenge, however I can't see how I can translate that into a legend.  I put together a really quick mock up of what I'm trying to do.
