@paul_gibsonAh that's a shame about the product development timetable. Hopefully if this thread gets some more traction it might be pushed forward!

过程方法的问题是当你have a large model with many user input requirements it is very burdensome to have to create import actions (and error-prone) for every data/ input module which is dimensioned by version. It could even become a problem if other developers are not aware that this approach has been taken since it would be easy to add a line item and not update the relevant copy action.

I agree the workaround is effective for smaller models where the same functionality can be achieved with a process however to be 100% confident in a copy with a large model I personally would feel more confident with copy branch.
