Plugins management - problem with reverseshell_stager_server

[Sirbu]

Is your feature request related to a problem? Please describe.

I cannot manage my plugins the way I do it with listeners. I cannot kill or list the started plugins.
My problem arises when I use the reverseshell_stager_server plugin. If I start it, it will listen to a port and « run » like a listener, but I cannot kill it to free the port.

Describe the solution you'd like

I would like to be able to see/list how much reverseshell_stager_server are running, how they are configured and their ID or something else to kill them.

Describe alternatives you've considered

For the moment, my only solution is to restart my Empire service to kill ALL the plugins.

Additional context

For more context, I was following this article explaining how to use Metasploit stager with Empire :

Maybe I am missing something, but I cannot find any information in the documentation for that.
If you need any screenshot or additional information, feel free to ask.
