Yes, i tried and had exactly the same problem, unfortunatley there is absolutely no documentation on this at this time. I recall an issue with in an old post where @patrick was going to make some changes so perhaps he could enlighten us as to exactly how to pass multiple dynamic waypoints.
I will be happy to prepare documentation and a video if we can resolve this issue
(Found the old post which was related to the data format of parameters passed to it:)
EDIT: .js file indicates it needs an array of string, maybe the changes indicated in the old post never happened as they are all still type:string)
