### Description

#### What problem are you trying to solve?
I'm trying to expose more of the functionality of blocking of services to HomeAssistant. In order to do that it would be useful to be able to send enable/disable commands for an individual service instead of having to get the active list, then add/remove the one I'm trying to do and then send the list back.

#### Proposed solution

Currently there are commands to get the list of services, the list enabled, and set the list enabled. There does not exist a command to interact on a singular basis.

Proposing commands list

/blocked_services/enable [ list of services to enable ]
/blocked_services/disable [ list of services to disable ]
