Change “no results found” in timepicker

Hi,
my client is using pro version of your plugin).

When time slots are used and no time slot is available for the selected date, the timepicker will show “no results found”.

When using hours instead of time slot, the current day is hidden and timepicker won’t be shown if there is not available hours for pickup or delivery.

Is there a way to have the same behavior for time slots ? (disable current day if there is not available time slot)

Or any way to change the text string “No results found” inside timepicker ?

King regards,

Fabrice
