Deleting Assets or Catalogs

I am about to start some prelim testing with bulk import of assets. In the event something goes sideways, I’d like to undo anything possible imported into the DB. Most of the existing documentation within this forum seems to indicate that removal or assets and/or catalogs isn’t supported with the shredder tool. This still appears to be the case under RT5. Is there any way in which a catalog or asset can be removed once created?
