Automated Daylight saving switch for Main IVR Custom Rules over multiple regions

Useful for Cloudflare inbound Sales call routing to auto adjust hours in the Main IVR Custom rules for each of our 3 world regions

For PST -> PDT and PDT->PST changes we have to manually adjust the working hours for UK and Singapore (APAC and EMEA regions)

Ideally there could be a second and third option for Date/time in custom rules under the Main IVR to allow it to toggle at a user defined date/time to match regional Daylight Savings Time adjustments for each region.

I'm happy to demonstrate as it will save me having to create multiple rules for the same region to cater for DST and then have to have a calendar reminder to activate/deactivate rules for each DST instance.
