If you add the info in each item's extra fields, you can simply call *specific* extra fields (and not the entire loop) by using the extra field alias value. More specifically:

=== Call specific extra fields in K2 templates ===
To directly output individual extra fields in your K2 overrides, do something like this (e.g. in item.php) to get the extra field name:
To get the extra field value you would simply do this:
Simply replace EXTRAFIELD_ALIAS_HERE with the actual alias of the extra field you wish to output.

In modules, use:
This way you can call any URL wherever you want inside your item.php template override.

The code does not work in a custom module because it's out of context. "$this->item" refers to the current K2 item being displayed by the K2 component. That's why you can utilize this code in the item.php override.

If you want to use this code in a side module on the item view or elsewhere, you'll need to get the item ID from the request/URL and then perform a custom query, parse the results to load extra fields and then render the field you want. Which is probably overkill... However there are ready-made modules that can load item elements, so your best bet is to find one and override it with the code I gave you.
