Voice command to remove all characters delimited by a given character in Dragon NaturallySpeaking

Is there a voice command to remove all characters delimited by a given characters in Dragon NaturallySpeaking?

For example, given the string ax.set_xlabel('Number of computed F1-scores', fontsize=fontsize) and assuming that the mouse cursor is placed on between the p and the u in computed, I would like the voice command to transform the string into ax.set_xlabel('', fontsize=fontsize).

I use Dragon NaturallySpeaking 12.5 professional on Windows 7 SP1 x64 Ultimate.
