It would be nice if the Combination Filter of a multi-configuration/matrix job could be specified via a parameter, or to have the contents of a parameter inserted into a part of an existing Combination Filter. The typical $PARAM notation could be used.

We have a large matrix of configuration, taking several hours to run. If one configuration fails, it would be nice to go back and test just that configuration. Hudson-5623 (http://issues.jenkins-ci.org/browse/JENKINS-5623) addresses this same issue. But if that particular issue is too difficult to implement, a configuration Combination Filter would work for us.

We could use a separate up-stream job to get the information from the user about which configuration to run again, then pass it to the matrix job as a parameter that could be used in the Combination Filter to directly target that one configuration.
