restapi: change variable value in app data load editor

[jsteenkamp]

We have automated all tasks in Powershell to onboard new customers like:

• add value to custompropertydefinition
• create tag
• create streams
• create user
• link tags and customproperty values 
• duplicate apps
• create app reload task including schedule
• publish app to stream
• update virtualproxy

There is one step, that I can't find in the documentation (if it even exist/or is possible).

Before publishing the duplicated app, I need to modify one variable value in "main" in the data load editor. In the GUI this points to URI dataloadeditor/app/{id}. Can this step be automated as well in some way?

Any help is appreciated. Thanks in advance.
