ok, so they need to sort this out.
but think there is a work around for this.
In IFTTT you can add alexa.
you can then just say "trigger test flow"
This triggers an IFTTT(that is set up in IFTTT), which in turn can trigger a stringify flow(what ever you set up).
This does mean all the logic needs to be there(stringify), instead of a routine.
But it is the closest we can currently get, and only adds the additional "trigger" word
