Do Not Water date for zone

I have a date in the near future where I do not wish for a zone to be watered as I’ll be using the area for a party.

Is it possible to flag a zone “DO NOT WATER” on a specific day/series of days within an existing schedule? I’ve just checked the app (via web interface) and didn’t see anything, nor did I find anything in a (very quick and cursory) search of this forum.

Thanks in advance,
