Ignoring the incorrect.txt file for certain trials?

[I][edited from support email][/I]
Is there a way to get DirectRT to ignore the [I]incorrect.txt[/I] file for certain trials? I'm requiring correct answers for one portion of my experiment, and so have an incorrect.txt file in my folder, but later in the experiment I ask a few questions with multiple correct responses (e.g. a 1-6 scale), and DirectRT is only allowing the first response option. Any suggestions for this situation?

Currently there is no way to turn the incorrect function off and on within a single input file. What if you used [I]rt:num[/I] for those multiple choice questions--that would make any number key a "correct" response. Of course, that would mean 7-9 would also be accepted but if that's ok, it could be a workaround for now. [I]rt:any[/I] would also work..
