I would like to create a dropdownlist in my customized program node user interface just like in move program node, which can get the configuration from Installation Node.
Is it also possible to get this “set waypoint” button?
As you have correctly observed, this is not possible in the current release of the API (1.3).
I have moved this topic to the Feature Requests category.
You are very welcome to elaborate the use case, which will help strengthen the feature request.
Other developers with the same requirement are invited to elaborate on their use cases as well.
