Is there a way that extension packages can be installed using the "administrator" client option or similar in a manifest file? I've made an installer package purely for the backend and I'd like it to show up under the 'Administrator' location in the Extension Manager, but it currently shows up under 'Site'.
I've tried adding a "client" property set to "administrator" in the element, but the docs are evidently accurate when they state it only works for components. I can work around by modifying the database on install using a scriptfile, but surely it's possible using the manifest alone?
