[Event Registry] Is it possible to link a channel to multiple events?

In order to link a channel to a couple of events I tried the following:

 "channelEventKeyDetection": {
      "fixedValue": "testEvent1",
      "fixedValue": "testEvent2"

This always results in only the last one working(no matter which of the two that is, separately they both work fine).
Am I doing it wrong or is there no way to do what I’m trying to accomplish whatsoever ?

Only one fixed value is possible. You’d need another channel model to capture the other one.
