Has there been any further development with this? A scheduled clean up is about to take place but I am unable to see which campaigns will be a affected.
Dan Stevens I was looking into the same thing and Marketo have updated their documenation (not sure when this happened) Adding a Program to an Engagement Program Stream - Marketo ...
I also think an easier way to keep track of the forms would be to include the form ID in the name of the actual form in Marketo. I think I will add this to our naming convention.
