Actually, it shouldn't take any more to create the items with one key 
and different ids.  For instance, instead of creating something like:

   <input type="checkbox" name="deleteField1" value="on">

You create

   <input type="checkbox" name="delete[]" value="Field1">

You can call your major and minor delete checkboxes different names.

In this case, all the checkboxes with the name "delete[]" will be in 
$_POST['delete'] array, i.e.

$_POST['delete'][0] might equal 'Field1',
$_POST['delete'][1] might equal 'Field3' (Field 2 NOT being checked)
and so on.

I find related checkboxes (i.e. similar processing for all) to be much 
easier to handle this way.
