Can you add a phrase list to the CallMediaRecognizeSpeechOptions class when using speech-to- text cognitive services from azure communications service

I am using ACS to access a multi-service Cognitive Services endpoint and doing recognition of speech input in real time via acs/telephone. I am using the default model provided by Microsoft. This is sufficient in most case but I have some place names that I would like to recognise (< 20) and from the documentation I think a custom model is overkill. I would like to use the "Phrase List" mechanism but I cannot find a way to inject the PhraseList, containing my 20 or so place names into the speech recognition process.

Is this possible through the call-automation api ? I am using the JAVA sdk.

    @John You could use phrase lists with the Speech Studio, Speech SDK, or Speech Command Line Interface (CLI) but I do not see an option to use the same with ACS SDKs, The reference for Java SDK does not document this. Also, it is also natively not supported by the speech REST API. Thanks!!
