Change availability calendars for specific periods

It'd be great to have a feature that allows me to use a certain availability calendar on specific days/weeks.

I travel between two different countries in two very different timezones and now I have to manually block off my phone calendar or change the available hours on Tidycal.

Availability calendar 1

  • set from 30 May until 18 June

Availability calendar 2

  • set from 18 June until 9 September

Something like this? Maybe with the option to override specific dates?
