You can now convert all of the project tasks into subtasks of another task. Create the task you want to put them in, then multi-select, convert to subtask, select the main task.
This worked. I used my laptop and had Premium free trial (not sure if it makes a difference).
In my project, I create a task called MASTER TASK of ____.
Then I selected all my other tasks that I wanted to covert into subtask (selected by clicking on top task that I wanted to convert, and then holding shift and clicking on last task).
Once selected, I clicked on the 3 dots on black horizontal menu bar that populated below, I selected convert to subtasks and tada!
I recommend creating a play or test project and have fun!
