Add scheduled: field?

What it says on the tin.

I’d love to be able to set a scheduled: date on a task via the iOS app.

If you don’t want to clutter the main task view, I’d be happy to have it on a ‘more fields’ view or something similar.

Start by locating the iOS app's task-editing entry point and reviewing how existing fields are presented in the main task view. Check whether a more fields view already exists, then trace how a task date is saved. Done means a user can set a scheduled date from the iOS app without obscuring the main task view.
