help with "values of options of select dropdown" in community builder registration

I explain.
in this url: abcdefg have a registration form with "comunnity builder", there I have a golf select type for countries in there a few countries, and here is the issue: that as intervals of the options we need to have the abbreviations of countries.

for example:

inspecting the code appear as follows:
<option value="Argentina" id="cbf36">Argentina</option>
<option value="Bolivia" id="cbf37">Bolivia</option>

I wish that the code is displayed as follows:
<option value="AR" id="cbf36">Argentina</option>
<option value="BO" id="cbf37">Bolivia</option>

You can make this change, how do I do it?

thanks, hope your kind reply.

When posting please always give your Joomla/CB version numbers.

With CB 2.0 you can setup values and labels of field options.

Sorry, my version is 1.9.1 community builder.
Thanks for the video, I'll see what corresponds.
Greetings.

seems that the videos are made for CB 2.0, it works for CB 1.9.1?

Nope - only CB 2.0+.

ops !, and as I do to achieve what I want in CB 1.9.1 ...
Should I perhaps first upgrade to CB 2.0, right?
