Allow workspace owners to manage idea portal spam

When you have a large number of workspaces and ideas portals it is challenging to effectively manage spam. We would prefer for each workspace owner to be able to manage the spam associated with their portals. These users do not need account level admin permissions and we do not want to grant these permissions just for managing spam. It would be great if the spam management was available in the workspace settings so we can more effectively allow each team to manage their own portal spam.
