Would love a way to add task to you inbox more easily

Right now, as I am aware, in order to add a task to your inbox you have to add it to your timeline, and then drag it to your inbox. This is very inefficient and I would love to use the inbox as a simple to do list for organising my plans, before I set it out in a timline. Right now the inbox is so inefficient to use that I do not even use it at all, it’s a waste of a great feature.
