Is there a good way to eliminate clutter after a build in SLRT?

I'd like to automatically eliminate clutter left around after a build in SLRT. For example, the slprj folder, the various .m files (...bio.m, etc.), and the hdl_prj folder. I know some of this is left behind to facilitate faster future builds, but I'd like to have the option for these files and folders to go away after a build. Is there a setting or option that would facilitate that?
