Describe the feature that you would like added

Currently, DateTimePicker allows customization of the picker toolbars through DateTimePicker.Titles. Would it be possible to add support to have custom left/right navigation items for the date picker as well?

What component or utility would this be added to

DateTimePicker

Have you discussed this feature with our team, and if so, who

No

Additional context/screenshots

For our use case, we want to include the "Remove" or "Clear" button on the date picker so the users could un-set the selected date. In the case that the date hasn't been set, we want it to include a "Cancel" button. Currently, the only way to dismiss the date picker is to pick a date or tap outside of picker area, I think it's a bit more user friendly to have a dedicate cancel button.

Idea: Due to varies use case of the components, perhaps it's more flexible to introduce a new component for the date picker toolbar, something like FluentUI ToolBar/NavigationBar component. The wrapper classDateTimePicker.Titles is not very intuitive as there are too many titles/subtitles, and it gets a little confusing. I actually have to try out some test string on the properties to figure out where they are applied.
