Ditto within Ditto?

Evening,
I need to sort Ditto results by geography, so I'm filtering by a TV "City" and upon these results I need to apply a further filter to group them by type eg:

Results For Scotland

Type A :
Edinburgh
Glasgow

Type B :
Motherwell
Inverness

//

And I'm not quite sure how to achieve this! Ditto within Ditto? Working with EVO.

I've tried adding PHX to the Ditto template though obviously I get this (repeated headings and not grouped):

Type A :
Edinburgh

Type B :
Inverness

Type B :
Motherwell

Type A :
Glasgow

/ Any ideas?

Cheers.

Filtering, or sorting? If you're sorting, the &orderBy parameter can accept multiple entries, such as &orderBy=`type ASC,city ASC` to order by city within type.

It helps if you show the whole Ditto call you are using.
