Using a point shapefile, I want to symbolize features based on a field: P_COMMOD.

I only want to symbolize certain values:
- ACTINOLITE
- AMETHYST
- ANTHRAXOLITE
- ANTIMONY
Is there a way to only symbolize certain values like that? For example, is there a way to add or remove specific values from the symbol list?
I would prefer to do it in a single layer, rather than using separate layers with separate definition queries and separate symbology.
Thanks.
