Rest_command cannot have a label

Unlike many of the other settings in configuration.yaml, rest_command cannot have a label, ie:

sensor temp:
   ...
sensor light:
   ...
switch light:
   ...
switch heat:
  ....

I’d like to be able to group my components by what they control, rather than component type. Looks like the rest_command won’t allow me to do that as you can have only ONE component entry.
