how to delete duplicate brushes more than one at a time

[karenproft]

I need to delete masses of brushes that I have duplicated.  I only see how to do it one by one.  Isn't there a way to do it like a group or more than one at a time?

Use The Preset Manager highlight the loaded brushes you wish to remove the click delete.  You can load Brush ABR set from there too.
