When using 'Add Choice' to a flow step your presented with IF statements to use.
Program Status can be used for example on the Send Email flow step and add choice and use IF statement value of 'Program Status' IS and use progression of Webinar > No Show. Then use the default for the Attended email.
This is how we have been using it, until the new MCE modual, that value of 'Program Status' is now missing!!!
