Adding a phrase list to the speech recognition request in azure communication services

Question

Is it possible to add a phrase list to the speech recognition request using the ACS call automation sdk?

I have about 20 place names that I would like to add as phrases to the recognition process but I cannot find a way to do it via the call-automation java sdk?

This call is the only access point to the speech recognition environment via ACS

CallMediaRecognizeSpeechOptions options = new CallMediaRecognizeSpeechOptions(iJourney.getTarget(), Duration.ofSeconds(2))

.setInterruptPrompt(false).setPlayPrompt(iPrompt).setSpeechLanguage(iLanguage).setOperationContext(iContext)

.setRecognizeInputType(RecognizeInputType.SPEECH).setInitialSilenceTimeout(Duration.ofSeconds(10));

However I don't see any option to add a phrase list. Is this possible or planned ?

Is my only option to build a custom model using "Text based data" to add the place names and then set the setSpeechRecognitionModelEndpointId()
