Hello everyone.

Tell me please, how can I bind (replace) my function to a standard command, for example, add.set?
(execute my function instead standart command)

Thanks to all.

I am not sure I get the question - can't you use the before.choice and run your code, then just stop the command. Normally I use choice.user sections or maybe I add additional code to a section, but never tried to completely redefine what happens in a choice. Maybe if you post more information on what you are trying someone will have a suggestion.
