Go to analyze, filter, and just check all the RTs you believe are above or below your cut-off. (for Simon tests, I usually do between 200 and 1000 ms, for example) - select lowest RT above criterion, hold shift, select highest RT below criterion) and filter. There's a lot of literature on how best to filter (what ranges, and such, IQR, +- 2SD), but typically, the results remain pretty much the same if your experiment is okay anyway and there's even a good deal of support for just using a criterion (such as my example).
