Pods Framework limiting duplicate entries

Hi everyone,
I’m just starting (again) with Pods – and really loving it!
I have created a custom post type that lists people who are involved in a project. One of the fields I have created for them is a reference to their country. All is working fine.

What I am trying to do, with shortcodes and widgets is make a reference to the countries that does not show any duplicates. By this I mean, I have several people in the Netherlands, and when I use the following shortcode, I get ALL the references to Netherlands.

[pods name=”coaches” orderby=”rand()” template=”coach locations”]

What I would like to be able to do is only have the Netherlands referenced once, so I tried using ‘unique’ to no avail, and various other limits.

Can anyone give me any pointers on this? And I am firmly committed to using shortcodes here, rather than creating a pods page.

Cheers and thanks for any help to get me on track again….
