Custom Region-based Configuration for Tmomatic Rules

Hi and thanks in advance for your timely support. I recently switched from having lots of genre-based rules truing to fetch concerts worldwide to 6 regional rules. This is working smoothly in terms of pulling concerts from different countries with less API calls, but we are forced to assign genres (and post in the relevant category) with a script which is not 100% reliable. Attached are a screenshot of 1 of the rules and the snippet function that currently tries to detect the genre. Would you have a different configuration to suggest? Thanks again. Leopoldo
