[pymvpa] how to ignore subsets of data?

Apologies if this has been covered already, I couldn't see anything about it in the archives.

Is there a simple way to tell PyMVPA to ignore whole conditions? I have 12 conditions, all of which occur in each chunk, and I want to use only a subset of the conditions in the classification analysis. Since I'm planning to run several analyses each using a different subset of the conditions, I was hoping I could tell the toolbox to ignore some of the conditions (perhaps by changing the labels, for example?), rather than having to create new 4D files each time?

Thanks very much,
