Show/Hide Channel Categories

I want to use one community setup for all 3 of my programs instead of having to sign up for multiple Heartbeat accts. A workaround for this would be the ability to show/hide specific channel categories. We already have the ability to show/hide channels, so if we could hide categories as well I could have separate categories only show for certain programs. She attached GIF of the area I mean. Simply adding a hide/show option to the category dropdown would be perfect!
