Show sub-category name in Category topic list via CSS?


Does anyone know if showing sub category names in the Category topic list is possible?

Context: I have regional-specific discussions which I group into the ‘Regions’ master category, and then within that I have each different geo in its own sub-category.

Problem: I show the homepage in the Category view by default. and the topic list in this view shows the title. The challenge comes when people put a post in e.g. the Boston category. But if they don’t explicitly label in the topic title [Boston], folks will not know that the post resides in the Boston category.

Question: Is there any way, perhaps via CSS, that I can add the name of the board, or a board identifier next to the title? I have looked into it and have not found a way so far, but I want to pose the question if someone has tried something similar.
