I'm looking for this capability as well. Getting a case of 'clickitis' in pool agent list view

I'm also looking for a way to add user defined capabilities to an agent via cli. Since GUI also doesn't provide a way to modify existing capability, just a way to add a new capabilities and delete existing capabilities. Deletion is not really needed but adding new one is useful especially with a script to setup a new self-hosted agent.
