Then, as Ignacio says, all you have to do is save the sub-sampled
dataset.
If the dataset is sub-sampled on a boolean criterion, the "store"
command automatically saves the subsample.
In the GUI, if you sub-sample then go to save the data, you're
prompted as to whether you want to restore the full sample first.
If you say No, you're then asked if you want to switch to the
reduced dataset (in effect, clear the old dataset and load the
newly saved version).
Allin.
