Is it possible to add various destination or page bases for URL structures in Themeforest?

Hi there,
I would like to use the ‘destination’ feature in Themeforest travel template, but for a variety of topics that are not necessarily related to destinations/countries/ cities ie.

I see that the theme allows you to change the destination base for the URL structure, but there’s only one field.

The same situation seems to apply to the page base, too (only allows you to set one category for all pages, like /info/).

Can anyone point out if the above feature exists? Or if customization is required, is what I’m asking possible, and is it expensive to do?
