Just override the form in the inlne admin. All you have to do is set a
default in the field you want.

In this case i prefer the approach of creating a "fake" field called
places, populated with the places, and when the user select the place,
you do an ajax request and populate the subplace select with the
subplaces from the selected place. You will have to override the form
in the ModelAdmin and add this behaviour to the form. Also you will
have to create a view to retrieve the subplaces based in the selected
place.
