Allowing for a comma delimited list of targets to be passed in

Would be nice to have this plugin accept Jenkins job build parameters from other plugins.  In particular the Extended Choice Parameter Plugin, which only allows for a comma delimited list to be passed into its multi-select parameter type.  I would like the multi-select list to be NAnt targets, but trying to use these two plugins together requires two additional build steps and the use of another plugin to massage the build parameter into a whitespace separated list.
