Limiting Mutliple Outputs doesn't work

[tiredofit]

In the configuration of multiple outputs it details how to show bars on specific outputs.

I have four outputs: output1, output2, output3, output4

• The following works to display on multiple outputs, showing on output1 and output2:
  "output": [ "output1", "output2" ],

• The following works to make it show up on output1 and output2 and output4
  "output": "!output3",

• The following does not work wanting to make it show up only on output4 and any other outputs that may exist that aren't explicitly defined:
  "output": [ "!output1", "!output2", "!output3" ],

It appears when using negation arrays are not read properly.
