get-csrgsworkflow and include text to speech for all questions

Trying to create a summary of the text to speech in the response group workflows along with other properties of the workflow such as name, description, etc.

This works great for the hunt groups,

Get-CsRgsWorkflow
| select-object Name, Description, PrimaryUri, DisplayNumber, DefaultAction,
NonBusinessHoursAction, HolidayAction, CustomMusicOnHoldFile

but doesn't include the additional text to speech prompts in the interactive voice response workflows.  There aren't get versions of the New-CsRgsAnswer, New-CsRgsPrompt, New-CsRgsQuestion, or New-CsRgsCallAction

I found Get-CsRgsWorkflow
| Select-Object -ExpandProperty DefaultAction from http://technet.microsoft.com/en-us/library/gg425766.aspx

but that doesn't include the additional text to speech prompts either.
