I do not believe filtering is supported out of the box by microsoft. The subgrids are pretty limited.

This article might help. The author has a method to build custom views with filters, simliar to the method of filtering lookups through script. It is an unsupported hack, but may be able to be adapted to your situation.

Another option off the top of my head would be to build a silverlight list-application or custom IFrame which would filter the list based on the selected option.
