Thanks! It would still be nice if there was a simple built-in method, though (or even a way to import the spreadsheet back in. If I need to use the API I probably might as well write the full feature to draw the data from the API as well.)

I asked about it in the webinar Q&A and was told a major server upgrade is planned to be completed by the end of the year at latest, which should massively reduce auto-action processing times (e.g. approaching real-time).

Actually, it seems as if Fixed Prices aren't suitable for this. I was thinking I'd be able to use them like a default for only when no daily price was set.

This is kind of a worrying issue because ideally auto-actions would be literally thousands of times faster to be well-suited for many common uses (e.g. to achieve 20 seconds instead of 20 hours would require them to be three thousand six hundred times faster). Currently if I was to, for example, use...

Is the best way to automatically extend availability a ~year in advance just to set fixed prices? Is there anything similar to Booking.com's "Copy Yearly Rates" where you just copy all daily prices from the past year to the next year, for example? Thanks.
