Advanced pass TIME CONTAINS date?

I'm looking to record an airing in the future and know the date and time it airs (2022-10-15@10:00)
The placeholder epg data for my M3U channel only has EPG for 48hrs, so I can't pick it from the guide to record.
I can create an advanced pass using
Channel ==
Time CONTAINS
But it appears Time only honors day of week and time, not dates.
Is there any way to specify Saturday, October 15, 2022 10am or 1665853200 ?

EDIT to add
I know there are many workarounds and the one I'm using is the curl manual recording method.
One could use TIME CONTAINS Saturday 10am, but that would record every Saturday.
