Set class help needed

I have an array of country data that I'm trying to adjust so it's
suitable to pass to FormHelper for select options with optgroup
labels. Set::combine has gotten me almost there but not quite.

Here's the data:

Array
(
[0] => Array
(
[id] => 1
[iso_code] => US
[name] => United States
[regions] => Array
(
[0] => Array
(
[id] => 4
[country_id] => 1
[iso_code] => AZ
[name] => Arizona
)

[1] => Array
(
[id] => 7
[country_id] => 1
[iso_code] => CA
[name] => California
)
...
[30] => Array
(
[id] => 63
[country_id] => 1
[iso_code] => WI
[name] => Wisconsin
)

)

)

[1] => Array
(
[id] => 2
[iso_code] => CA
[name] => Canada
[regions] => Array
(
[0] => Array
(
[id] => 6
[country_id] => 2
[iso_code] => BC
[name] => British Columbia
)
...

I tried:

$options = Set::combine(
$data,
'{n}.name',
'{n}.regions.{n}.name'
);

This creates:

Array
(
[United States] => Array
(
[0] => Arizona
[1] => California
[2] => Colorado
...
)

[Canada] => Array
(
[0] => British Columbia
...

What I require:

Array
(
[United States] => Array
(
[AZ] => Arizona
[CA] => California
[CO] => Colorado
...
)

[Canada] => Array
(
[BC] => British Columbia
...

Can anyone think of a way to do that with Set?
