Import task and subtasks from one cloud gantt to another

I have my main GanttProject which is saved on the cloud (“Main”).
I created another ‘temp’ GanttProject which is also saved in the cloud (“Temp”).

I want to import a task, with its associated subtasks from “Temp” into “Main”.

Is this possible, and if so, how?

Hello, this feature is not yet there, sorry.

I suppose I could export as a CSV or something from “Temp”, and then import that into “Main” instead?

In the desktop GanttProject you can just import one project file into another. It will make a copy of all tasks, but if that’s okay, it is easier than CSV.
