[Feature Request] Allow blank name for external command

[puterboy]

Currently, it seems that if the 'name' is blank then the external command fails to run/display.
I use the command to retrieve a couple of different temperatures along with the relevant labels so I don't need a separate "name".

The best I can do is to set the 'name' to a space, in which case it displays ':'

Desired behavior would be if no name and command exists, the run and display output of command without name or colon.

Thanks!
