You could have a column in your CSV called double (1 or 0) and a duplicate routine in your flow to monitor for the repeated key or end early if double is 0

Yes if you have a column called nResps and have it as 0 or 2. You could then add a code component to your routine (find under Custom) and add the following snippet to the End Routine tab:

if len(key_resp.keys) == nResps:
    correct = 1
else:
    correct = 0
thisExp.addData('correct', correct)
