Skipping a list level based on experimenter input

[Sean O'Malley]

This is an incredibly simple issue, I'm sure, but I don't know the right 
place to look for the answer :).

My paradigm involves presenting a series of three-trial task sets.  After 
the first two trials in each set, I want to ask the experimenter whether 
he/she wants to do the third trial or move to the next set of three.

I'm sure there's a standard method that does this, but all I can find are 
methods that cause an entire level in the structure to be skipped (IE going 
from block to session).  I just need to tell e-prime to skip a list level...

Thanks!
