Remove from the drop-down list if it has already been used within 24 hours

[wsaico]

I am using this expression NOT (IN ([_ THIS], SELECT (Yard [N FLIGHT], [DATE] = TODAY ()))) to avoid duplication, but I would like it better to be removed from the drop down list when an element has already been used in 24 hours is it possible to do this function?

Patio ([N FLIGHT]) → where the flights are registered and Program vlos ([Concat vlos]) —> referenced column for the drop-down list

I appreciate your help, I spent hours and hours and I can not make it work
