ability to hide certain inputs/outputs

[maricn]

i'm aware of the rename feature and ability to remove the name, but i'd like to completely remove some of the inputs/outputs out there through configuration or cli parameters..

reason: i have HDMI1, HDMI2, HDMI3, Speaker + Headphones and multiple bluetooth receivers + sometimes combined sink.. moving around all those can be challenging, and some of them I don't ever use, so it would be helpful to hide them..
