Allow setting default field value for update.

Right now when creating a new update the user has to pick a value for the field or fields on an update.

This is fine for many situations but for very common cases like scheduling a publish date the site builder may not want the user to be given a choice about the value of "Publish Status"

They may want the user to just to see a date field labeled "Publish On".

This possible now with the module if:
The default value of "Publish Status" on the Scheduled Update Type is checked.
The field is hidden on form display

Of course that is hard to figure out with documentation.

I will try to make an option to provide a default value on the Scheduled Update Type form if the user is selecting a field there(instead of cloning multiple fields)
