Request: Support more than 3 alternative timezones

I just bought an Instinct 2X, and I am very surprised it allows only 3 alternative timezones. Beside my own location, I have immediate family in two other locations, at least two other timezones that are important to see for work, and as a developer it is always handy to see UTC also. That's at least 5, and if I ever moved states I would need a sixth.

Why does a modern smartwatch only support 3? I can't imagine how timezones take any significant resources. It would be nice to see this limit improved on the next firmware. A reason I bought the watch was so I could pull my phone out my pocket less often.
