When adding streaming services for region-locked dramas, the only option is to list unavailable countries, but that isn't always useful since many region locks are excluding all countries/regions except a select few. So if a service is only available in, say, Thailand, Singapore, Malaysia, Philippines, Taiwan and South Korea, but unavailable everywhere else, there is no meaningful option for specifying that, which means it's left listed as available everywhere with no restrictions.
I'd like to suggest that it should be possible to add which countries or regions (e.g., "South East Asia" or "Thailand") where a drama is available on a specific service, or at least to add the option of "limited availability" without specifying which countries or regions.
