Hi NMullin,
Thanks for the follow up.
I do not believe there is currently a way to play a streaming scenario only once. I will see if this is something that can be easily added.
I should at least mention, that it is possible to use the API to transmit a waveform. The API is an interface for programmatically controlling the instrument without need for the UI application. This would allow you to perform this task relatively easy if you are comfortable writing software. See link below for more information.
