moment-timezone include all data for specific timezone

Based on the options for including timezone data there doesn't appear to be a way to include all data for just one timezone. We only operate in the UK but hold data going back 20+ years so are currently having to import 'all'. It would reduce our build size if we could limit the import to just "Europe/London|Europe/Belfast".

Is there a way to do this?

The issue names no file, test, or entry point; start by locating the timezone-data inclusion options and the path handling the current "all" import. Check how Europe/London and Europe/Belfast could retain their full historical data while excluding unrelated zones. Done means a documented, configurable build that produces a smaller bundle without losing the requested history.
