Feature Request

When using text-based experience, we allow developers to piggyback additional information to outgoing messages. This is demonstrated in sample 15.a "piggyback data on every outgoing activity".

With Direct Line Speech, you can no longer piggyback additional data to all speech-based outgoing activities.

Note to dev:

Web Chat warnings also need to be updated:

https://github.com/microsoft/BotFramework-WebChat/blob/master/packages/directlinespeech/src/createAdapters.js#L124
createAdapters.js warning needs to be updated to remove userId check.

Moving this to front-burner.

Is this now supported by using the SpeechActivityTemplate property? Sharing the link for the .net SDK. https://docs.microsoft.com/en-us/dotnet/api/microsoft.cognitiveservices.speech.dialog.dialogserviceconnector.speechactivitytemplate?view=azure-dotnet

This was introduced on Feb 2020. https://github.com/MicrosoftDocs/azure-docs/blob/master/articles/cognitive-services/Speech-Service/releasenotes.md#speech-sdk-1100-2020-february-release
