I think it is limited to container level as, if you have an account temp URL key, and you have a DLO/SLO, you could just generate a temp URL for each segment of the DLO/SLO and get the data that way.
With a container level temp URL, your container key would be no good to generate a temp URL for an object in a different container, unless that key was also set on that other container.
