Gantt view > right click on a task, can't see the "add subtask"

Hello, why isn't it possible to add sub tasks out of Gantt view when right clicking, while it's possible in Table view. This forces us to swap from one view to another and loose the location we were editing. Have to open lines and search for the tasks to add sub tasks echa time you swap from a view to another. Pretty anoying. Thanks.
