microsoft project training course london - Sort Project Plan By Date

One of the directors would prefer to see the project plan sorted by dates only instead of workstreams /departments as the project is currently sorted for other purposes. I have tried to do the sort by start date option, but it is not sorting the entire plan by the date. I believe it might only sort them within the particular indentations.

Is there a way to sort the plan out by date regardless of what department they belong to or whether they are indented?
I would need to send this as a regular report, without permanently changing the way the project plan is currently set up.

Many thanks
